The older Briggs L heads hold such a steady rpm, I love all the models, 14,17,19,22&25, from the 60's up to 1989. Before they started using foreign carburetors.

Can't get enough of your videos i love small engines and working on them. Keep up the great work!

I love watching these 'will it run series ' on a rainy day/night while in my garage working on my old vw veedub! Nothing better than the feeling of a ratchet in my hands & a cup of good coffee & my virtual buddy mustie keeping me company in the background! 😊 Awesome!!

Your knowledge and description of what you are doing is excellent! Thanks so much Mustie.

Thanks!! I've watched this video four times now. I really like these old Ag-Tronic or Coleman Powermate generators made in Nebraska. I use one to power the entire house when there's an outage. Aside from having to gas it up every 90 minutes, it's a very well built unit and as you can see Mustie has shown that it's totally repairable and the parts are very durable. Change the brushes, clean the carburetor, replace the recoil spring and rope. Lube the starter ratchet and you're good for 50 years, no kidding. Mine is almost 35 years old, has a few hundred hours on it and it may go another 35 years for someone some day.

Thanks for showing the inside of the pull start ratchet as well as the float boat leveling by bending the tab. Really appreciate how how you explain everything!

Hello my names Tony and i use my wife's e mail and watch her you tube i really like watching you repair old unwaned machinery keep up the good work and the fact that your from NH is a plus thanks

Thank you. I appreciate your hard work, perseverance and relentless effort to bring a dead unit back to life. Bravo. Cheers.

Hi, the problem with the pull start most times it is the recoil spring, I always remove the pull starter, blast the spring out with air then reset the spring tension, to spin the motor over without the pull start, I use a 1/2 drive socket that fits the spindle I also use a 1/2 drive socket attachment that fits into a large size power drill, using these tools will help spin the motor over to check for spark and also start the motor, hope this information helps you for future work, I also enjoy watching you work on other petrol driven machines. Kind regards Sam Knudsen. Adelaide, South Australia, Australia

I like my old school stuff, I have a 3 1/2 horse Briggs lawn mower engine with that same type of updraft carb. It was made in the 1950's. It's got points. I fix my own things as well. Enjoy your videos Sir great work.

Oh I wish I had these videos when I was young. So much fun to watch. No more boring days :) Thanks Mustie for making these!

Great explanation of how the pull start works 👍 Love watching you fix things Mustie 😊 I sit in my truck most days watching you great show lol 😆 Keep it up please Stevie 🏴󠁧󠁢󠁥󠁮󠁧󠁿

Thanks for doing this video. It helped me bring my (late) Granddad’s Coleman PowerMate 4000 genset back to life. Hasn’t run since the mid-90s. Carb was clean, except for a couple jets. Surprised how quickly I could get it sputtering. Emulating your fuel-air mix adjustments got it running. Just now shut it down, after running for nearly an hour with a 1500-watt heater load. I cut the fuel off so it ran out of gas, drained the carburetor and siphoned the rest from the tank, per your suggestion. Gonna test it again in a week to see if it starts easier this time. 💪 Thanks again!

I have an old Agtronic a lot like that, but bigger, 16hp Briggs & Stratton with 4kw gen. Picked it up from a farm estate I helped liquidate. It worked when I got it, but the carb has gummed up from sitting. Mine has a manual wind pull start though. And I haven't hooked it up, but it appears to have battery powered start too. Thanks for making the video. It'll help when I fix mine.

My kind of therapy is watching small engine repair. Love it!

Reality video is the best approach to actually see what we go through. Great info and easy to understand. Thanks for sharing.

Great videos wish I had time for all the projects you tackle! Many meters have a frequency counter. This helps more on the loaded RPM adjustment than voltage.

I like all of your projects, I enjoy bringing old equipment back to life.

I love how you save all these old machines with just basic care and tune-ups. If people would take time to read the manuals of the equipment they buy and actually maintain them as suggested their lawn mowers, tractors, and any gas equipment would last for ever. I guess that's why we have endless supply of cheap (very expensive) stuff to maintain or buy and find for our profit!

the "kill switch" is the short tab on top by the spark plug, I have an 8hp Homelite with the same "kill switch".

These videos are great....you have the right patience and skills for these kind of jobs !!

The engine whisperer.

An oldie but a goodie! Sadly generators even smaller ones like this one are no longer made. They just don't make them like they used to. Awesome video! Much appreciated

Solid genny. Love those old Briggs motors. tough as nails. I like the simplicity of this one too, not like the newer ones that are overly complicated and cheaply made

I am amazed at how clean that carb was!

I have two of those, they've been sitting for years (have a Generac now) but would back feed from the garage 220V to house (don't forget to turn your main off) to power the sump pump and basics. Some mods I did, upgraded to the larger plastic tank that sits on top of the chassis - either tank option, you'll be filling up the tank every 1 1/2 hour, so little sleep if you plan on using for any long period of time. They are LOUD, tried to retro fit a small car exhaust to quiet down, but still loud. Added wheels/axel to motor side of chassis for easier transport. Overall pretty good generator, brushes were hard to get years ago.

Mustie1, I first came across you in various VW videos ... very engaging, but a bit over my skill level. This video, however, is perfect and I want to get a similar generator running. Thanks for showing so much of the details as it will be invaluable as I attempt my project.

Good old machines! I had a yellow colored "Skil" gen-set identical to that. Vibrated a lot but nice and simple.

4000 watt ? 544000 rebuilding one now 8 hp briggs and strat. . good video, thanks very much ! I was lost on the carb with the needle/seat going through the bowel into the carb itself. This helped. Thank you.

I just bought a coleman powermate 5000 from auction and came across your videos and many hours of vids later, im hooked. I don't mind that some videos are longer than most. Very cool videos. Keep it up

Hi Mustie1.Thank for sharing.I have a 10HP Briggs 4.500kw generator that I curb find down the street about a month ago.I did the same as take apart the carb and cleaned it which it was not bad.,Replaced rotted gas line to the tank. The recoil was ok.The generator head was not working until I cleaned and reseat the brushes.The voltage measurements were great and I did a load test with my 3.5hp Craftsman chainsaw and a light for about 2 minutes and the generator did not struggle with the load. I think the reason why they got rid of it because it was not generating power because of the brushes were not seating right.

nice to see someone actually clean up a Briggs starter clutch instead of just replacing it. I haven't had one yet I had to replace

Thanks Mustie, I had one just like it, powered my fridge and some lights and other stuff when my power was out for 5 days back in 03 because of a storm.

I love having 'Ol Krusty in the background! Such a cool truck!

Nice fix, I love those old engines.

I had one of those and it was a 4000 watt version. It was dead though. The engine ran but no power output and the generator itself was open circuit. Bought a newer 5000 watt Homelite, got it running and producing power and I love it!

great job as usual. too bad you received the incorrect part for the tundra. your videos are always interesting to watch.

Great video. You have a lot more patience than I do, as soon as I saw I had to rewind the pull start by hand I would've called my friend and said, "Nope, she's dead"; I hate those things.

It never ceases to amaze me how those much maligned Briggs & Stratton engines will take years of abuse and still come up trumps. We used to have, and still should (somewhere), a 'special tool' for removing those starter ball clutches from B&S engines, though I have seen guys using a hammer and parallel punch to strike against those little lugs - not really a good idea! Anyway, I'm sure I've seen that, or near identical square bodied generator sold in the UK in the early '80s. Painted white and carrying the brand name "Conyers", and still as a 110V/220V, but 50Hz as you would expect in UK, and equipped with UK sockets. A note on the float! - The golden rule, as written down in the B&S manual of the time showed the float as being correctly set when the float's top surface was parallel to the the face of the float bowl top cover. In plain English, we always referred to that as being "level across", so you're spot on in your setting procedure. I guess the fuel level isn't absolutely precise, and if you take into account, vibration, uneven ground and anything else that would upset the level in the bowl, then nor can it ever be, so there has to be some degree of latitude.

Very good video, one thing on generators is that it is important to get the RPM properly set so the frequency on the AC is at 60Hz, if your multimeter reads frequency just insert the leads into a receptacle and adjust the RPM as needed to set that frequency, a very knowledgeable person told me that years ago, Thanks, Dave

I just got one just like this and with your help I got it running again sweet! Thanks

You have that reassuring tone that makes it seem like anything is possible: "Well I got this prehistoric lawnmower for a buck. Let's see what we can get it to spark." Very entertaining and educational.

My word this is like one of my favorite channels on youtube, no joke Mustie is a smart fella!!

I used an old 1/2 drill with a socket that matched the flywheel nut, it allowed me to start the engine, Worked, might help you sometime on a motor the return rope did not work, Enjoy watching your videos,

We had 1 of these COLEMAN powerplants back in the 1980s and up until 2013. VERY reliable it was. 4 days after my mom bought it, it blew the 5 HP B&S apart. My mom ordered a new 5 HP B&S engine only to get a 6 HP B&S Industrial/Rental Duty 1. That thing lasted a long time. My step brother traded it for drugs back in 2013.

Those old engine used a metal tab mounted to a head bolt that ground out the spark plug as the kill switch. Mine also did not put out power when running but the slightest turn of a drill chuck while plugged in and it was off and running.

I don't know if I'm just showing my younger age *36* or not but man I've never seen a carb on anything that was painted the same color as the machine , that's something new for me, kinda different . I guess In the days where they built things to last they also put more attention to the little details, even dressing up a carb with a coat of paint lol .

We have one exactly like it at the fire station. It runs like a champ, starts on the first pull every time.

Nice work I have the same motor on my generator but mine is a 4000w gillette. And I am about ready to tear into the carb to tune and clean it all up.

i had the same one yrs ago. it had a metal tab to ground the plug out and thats how you would shuter down. but mine had a 3500 watt northern hydraulic generator strong briggs too. would always start one pull. even after it sat all summer never did carb work and it sat for 15 yrs prior to me getting it.

Nice fix Darren! Cool lil generator! Great for bar mitzvahs! :D

Mustie1 Your channel is really Good. I love the way you laugh. You have a gift for engines. The good of the Land channel has a show The incredible gasket Maker, I knew he’d be interested in that. Keep up the great work!

To kill the engine push down on metal tab next to the spark. Push down till it makes contact with plug.

Super video. Great job, thanks for sharing.

Good fixes all the way around.

Man I really enjoy your videos and I used to have a CB350 that is one of my favs. Keep the vids coming.

I was given a generator with a Tecumseh engine. The fellow said it wouldn't run, I cleaned it up and got a Tecumseh engine manual. I set the points it fired up and ran great until the engine got warm and then it would speed up, slow down etc. I finally gave up, I later spoke with a small engine mechanic who told me the Tecumsehs with the heavy cast iron flywheel wore the bushing out on the flywheel end and when they got hot the points gap would vary wildly. He said replacing the bushing almost always fixed them.

Another great job. Keep it up!👍🏻

I got one of these green things, not the same but very similar. I laughed when you mention early in it doesnt have a kill switch as if it were a snake it would've bit you. LOL. Anyway got mine started tonight for good measure...That damn choke. I gotta put it in the middle to get it to go and any other extreme will just tucker me out pulling on the starter . Apparently these were around the early 90s it was my dads... so may be time to upgrade just for fault tolerance.

I have an Ag-Tro9nic 4000 54 series 33.3 amp generator. Mine would not put out any electricity when I 1st got it. I checked for free brush movement and found one was hung up. Took it out and rubbed the sides of it as they are nothing more than a pencil lead compound and made sure it moved freely inside the brush hood. Put it back together and voila! Other than that I pretty much always need to zap the field with a 6 volt battery tickle and make sure the drill rotates the right way. If not I switch the wires and reap the fields. I will need to replace the muffler and that is well seized so not sure how that will will go. Appreciate the video on an old but reliable generator.

Nice Job - hopefully you got a good price for it as its all sorted to give reliable service to the new owner

i recognize the pickup assembly, its a Hall effect inductive pickup-thats attached to the pull start.. cleaning the flywheel/rotor surface helps it start easier, run cleaner and more efficiently. ive serviced a LOT of lawn mowers that have that same assembly and they always run smoother & better & start way easier after cleaning that.

I have one of those Coleman's. It is about 15 years old. Yours has the better Briggs, mine has the Tecumseh. Good generators for running tools, etc.

We had a GenSet like this. Was a Coleman brand. Motor blew and we put a B&S I/C RENTAL DUTY block on it. 8 HP it was. Tough unit with the yellow motor. It was a 7000 Watt unit. We even did the same to the Troy-Bilt rear tine tiller.

I ended up tuning the speed of my generator using the AC frequency and found it worked really well (picked up one of those $10 ebay inductive tachs later and it agreed). I think the brand over in the states is "kill-a-watt", designed to tell you how much power you're using, they usually also have something that tells you about voltage/frequency. The frequency will be directly tied to engine speed on any non-inverter generator, some multimeters have a frequency setting too.

Good luck with the toyota tundra parts search. The generator sounds good.

Last time this generator was working was likely before ethanol blended fuel which likely explains the carb's condition.

Surprised it wasn't screeching like crazy when you first started it. One of the classic symptoms of a gummed up starter clutch. That would've sounded great on film!

Runs sweet Darrin , Thumbs up man !

Brings me back to 1990 when I was a B&S repair man.

Thanks....I got one of these green monsters,a video that actually shows a problem and tells me how to fix it..appreciate it

Neighbor was getting rid of old root tiller . Has exact same carb. Took apart cleaned and replaced points with electronic ignition I found on old lawn mower in trash. He bought a new 1000$ model that works like shit. Always feel bad seeing me use this beast free root litter.

been watching several of your videos. I really love it. but now I subbed cuz I really like watching your vids :)

Only issue I've seen with those is the power head shaft bearing at the end of the unit. The old ones might be OK but the newer ones aren't easily serviceable if at all. The housing the bearing goes into is plastic and spare housings are long gone... Nice quick fix.. Take Care

Another winner, great vid and tutorial.

Nicely done, looks like a good genny.

My neighbor was getting rid of his Coleman 1997 2250Watt generator. FREE! I knew I would get it working and I did. It was the brass float in carb. It had two cracks in it and filling with gas. Rebuilt carb and new float, runs like new again, won't tell him that! LOL. Can't find the owners manual on line though. Also put a new pull cord on too.

I used to work for Coleman powermate in Kearney nebrasks back in the 90s. Was the best job I had. Was on the final assembly lines.

Great videos. You are one of the most informative KZfaqrs in this type of video -- and an added bonus is that you don't fill the videos with foul unintelligent language.

Designed and built at a time when engineers actually considered taking the recoil housing off as general maintenance performed by the owner, so it slid right out. Now they would intentionally design it to not come out without dismantling everything else. The RMA warranty repair workers would have a special spreader to force the frame out just enough to get it out, 1/8" too much spread and the frame would break, voiding any warranty.

I saw powermate - that reminded me of our first new car - a 53 Chevy with powerglide !

u might be able to get a cup with the V cut in it. that makes it a vintage but it works.wrap a rope. can not be too bad as she started. wishing u good luck on this !

Testing voltage...wouldn't it be frequency you would want to adjust for 60Hz with engine speed?

Take the shroud off and put a socket on the clutch. Run it it with the drill. That is what I always do when working on those. Love the vids.

Thanks! I have the same generator and the starter assembly lack lubrication and screams a bit. Now I know how to disassemble and lube with lithium greease.

Hey that muffler you put on there , I bought two of them for my 22hp Kohler zero turn and removed the stock muffler but left the pipes and I welded one of those exact mufflers in the end of each pipe giving me a custom true dual exhaust , sounds pretty bad ass honestly , kinda has a Harley type tone to it. It is a bit loud though as I drilled holes in the center baffle to increase flow so they weren't too restrictive . Only cost me 14 bucks for my custom dual exhaust my neighbor's hate me when I mow my lawn . No police coming with noise complaints yet though so it's all good in my eyes

thank you Mustie your vids are great keep them coming.

Nice single cab! Seen it many times at Transporterfest 🙂

I have a Colman model PM0524000 Maxa Powermate 4KW gen with an 8 HP Tecumseh that is a recent find. It kicks over but I have yet to see if the head puts out the 120 /240 rating. Wish me luck. Keep the good vids coming. I learn a lot. Mel

the correct Lube to use in a recoil clutch starter is dry graphite lubricant it should also be used inside the ball bearings, should also clean and polish out the inside of the female into the clutch starter

all of those beautiful flat head engines in the hoard... a mini bikers paradise.

This looks like the kind I saw 50 years ago when my father was a building contractor. No Hondas in those days.

I had one of those. Float MUST be right. Also, as mentioned they do not like the new ethanol gas. This old model does pretty good except for the vibration making them dance all over the place.

I have that same generator. I haven't ran it in years because it just didn't put out enough juice that i needed when my power was out.

Love these old _Powermate_ generators.

Another great one! Thanks!

WOW I bought one of these Coleman new back in 1987. It had a plastic gas tank which cracked. Once the power was out and after a week of continuous use, the plastic brush holder got warm and soft enough so the brush got held up. Coleman paid to fix it under warranty. The upper outlet is split with both sides of the winding present in each half of the duplex. I was in in a pinch for 120-240V and didn't have a NEMA 6-15 Plug for the bottom outlet so I used two MEMA 5-15P's and got it out that way. ("kids don't try this at home" Good way to ruin equipment and get zapped by back feed) From the 2 plugs I made common the whites and greens like a grounded neutral and used the 2 blacks for the 240V to get 3 wires. This Ag-Tronic generator is not wound for slash rating 120/240V it is only 3 wire. It's like a three wire single phase service in your home and not a 4 wire sub panel... (short explanation) I would ground to the lug on the generator and never had a problem. Mustie1; I could check the speed with my frequency meter but I would need you to adjust it. :-) Great Vid! It sold for $499 new at the department store. They also sold a 5000 Watt unit but that had a Tecumseh engine on it and sold for $599. I went with the Briggs.

It would really be helpful to zoom your shots more. For example zoom up close when showing your work on the pull start ratchet. Seeing the whole work table doesn’t show us anything interesting. Roll the screen with the component. Keep bringing the generators to us. Very interesting and rewarding to be there when you fire it up!

Thank you for showing yourself messing up, it makes me laugh, and knowing someone else messes up the same way I do...makes me feel better.... . LMAO

That's nice simple generator.
