In the old days a father would send his son to ‘apprentice’ at the side of a mentor, who would not only teach the skills of his craft, but also impart wisdom and life lessons that are difficult for a father to pass on to his son without encountering resentment. You are the very definition of a new age mentor…a role sorely missing these days. The patience and perseverance you bring to your work is a gift that you share so selflessly, and exactly the kind of thing that can’t be passed on in a classroom, and something a student can’t be told…only shown! You are shaping men, young and old! Well done, Sir!!!

Hey Musty don’t worry about your video’s being to long. We look forward to your videos and if they are an hour and a half long it’s ok. We gladly watch till the end. Look forward to the next video. 👍🏻

I can't recall how I found this channel but it's been many, many years and it is still just as awesome of a watch as it was then. Hope we get to see a teardown cause they are always fun to see what is about to fail, or drain the oil and pin the throttle and let it die which is a fun watch too haha

I have a piston and rod that might fit if you need it. It’s used, but looks good. Will overnight it to you if you want to give it a try. Those typically have piston slap at lower speeds but it should go away at higher speed. I also have a GX390 engine with electric start you can have. The only issue is it has a tapered shaft for a generator. So would need to adapt it or swap the crank with your bad engine.

I think you should tear into that engine, make sure the crank and cylinder wall is ok, and if it is just rebuild that engine. Will be cheaper I would imagine and you've got everything set for spacing for that exact engine.

I suppose that, in hindsight, it might have been a good idea to test the engine at the very beginning of this build, rather than at the end of the first video. But once again, this video is a good lesson in psychology. Bad engine, but no tools thrown across the room….but a great attitude even though this didn’t turn out the way we anticipated.

When you drained the oil and it was so very thin I think that may have been a clue. It looks like perhaps the oil was contaminated with fuel and nobody noticed the problem until it was too late. By the time you got the engine it had been run for some period of time without proper lubrication to the bearings in the bottom end.

Good afternoon everyone watching from Lincolnshire UK 🇬🇧

When all is said and done, I would love to see an autopsy of that engine. Thanks again for an hour of good old-fashioned entertainment and learning.

Check the compression or examine the cylinder wall, that engine looks very new. I would investigate the cost of a new connecting rod, and possibly crankshaft too, depending on the surface of the bearing, if the crank is good, a new rod should be a fraction of the cost of a new engine. I'm a packrat too, and I'll save everything that isn't completely destroyed 🙂

Without doubt, there's never nothing to do in your world. Thank you for another relaxing and educational start to our Sunday morning. Best from CT.

At least you get another video out of the bad crankshaft. It may not seem logical but the setbacks and how you overcome themare just as good to watch as the wins, if not they're even better.

When you made this exhaust I wasn't sure how it would work but after listening to it crackle and shoot flames almost I understand completely. This is like a mix of old school, new school and everything else. Might not be working perfectly but I see the vision. Very cool. And it's crazy you made this up from your scrap.

Good ol uncle Rodney, always shows up at the worst time

That runny oil looked like it might have had gas contaminating it by way of a leaky carb letting gas run through to the case. Would have expected to see too high of an initial oil level, vs low, in that scenario too though. Worth at least draining the original oil to inspect it once an engine has proven it will run a few seconds on starting fluid too. Looking forward to seeing the replacement engine go in, fabricobble finishing touches and then you riding...and giggling...around on it! 🏎️

That big end is toast, as for the smoke they will smoke more on the heavy oil as the rings ride on the oil and don't scrape it off the bore properly. worth a better engine in the long run. Thanks for posting.

As far as the drain plug, I put an extension of pipe from the hole to the end of the frame and capped that.

My vote is for you to find another cheap engine and show what is necessary to get it up and running when your first plans don’t work out. Some of us don’t have the means to buy a new engine and need to make whatever we have on hand work. Just a thought. I really enjoy your channel. Thank you.

I would love to see an autopsy of this engine. And even though it likely isn't worth the cost, it would be fun to see a step by step rebuild of one of these "Honda" engines. Rod bearings, rings, seals and such are certainly available.

That's a shame! But it's never too late to change your mind on engines, have a look in your garden tractor stash and see what's there you could possibly use

I think it's called H&L supply, which is where I get a lot of my small engine parts. You can get a rebuild kit for most engines for 50 bucks or less at least once upon a time anyway. Go power sports, you can get a heavier set of valves springs so you can get rid of the governor. You will also want to remove the oil sensor in the case. Use a 1/4 in bolt to plug the governor hole it's been a while since I last built a go cart engine but I think it is a 5/16 or so to plug the hole for the sensor. Those engines can be rebuilt. Hella cheap or you can throw the bank at them. It can be stock horsepower or built up to close to 40, depending on how much you want to spend. Sky really is the limit, that's why them and the 212's are so popular in the go cart mini bike world. You can also get an electric start kit for it pretty cheap. That way, you can add headlights and stuff

Hi Mustie. This is D. What a bummer. That engine sounded great on last Sunday’s video. Loved the mid week video by the way. Looking forward to the skid steer and seeing what you are going to do with the cart. 👍👍👍

Good morning all from Pennsylvania! Mustie 1 you have become a Sunday morning in my household. Thanks again and keep up the good work!

What a great way to start off a Sunday! You're using motor oil as a cutting lube for a hole saw. A better choice is plain water with a few drops of dish soap in it. Oil reduces the friction necessary to cut cleanly; what you really want is to keep the tool cool to prevent it prematurely wearing. Another good cutting coolant is plain ol' Windex. WD40 also works well because it's not really a lubricant.

No matter what a mustie1 video is always good entertainment and learning. Come on Mustie1 let’s kick this in overdrive. Can’t wait to see you ripping up some ground on this one. Thanks

Sometimes you win, sometimes you don't. Looking forward to seeing a teardown of that engine to see what went wrong. Great start to my Sunday as usual, good job !!

Amazing fabrication on the carburator assembly and it is unfortunate that the engine let you down...my choice like you were saying would be the replacement clone from harbor freight or the more time consuming task of tearing down the old one and salvage it. Either way it will make for great content..as always I appreciate you sharing your day with us and it's always cool when you fabricate something outta the stash😊👍🛠️🇺🇸😎

I definitely want to see the side cover removed to take a peek at the rod cap, rod end and other parts. If it wasn't a matter of no or low oil it might have been loose rod cap bolts. I've seen that in new clone market engines. Can't wait for the next Mustie1 episode. Makes a Sunday perfect.

Although I don't have any clue about the terms used or engines or mechanics, I really like watching how you diagnose and repair faults on engines.

Cant'n whaite till you drive this cart / Buggy around ,,whit a big smile on your face 👍👍👍👍😀

Hey Mustie. I would strongly advise you to take the engine apart before replaceing it, often the con rod and pistons can be worn as they are aluminm and the steel parts survive. if this is the case it will be no more then 40 bucks to rebuild it, if the heads scored then another 80 bucks to replace that. as these honda clones all have the same parts they are easy to get and fix obviously the origional honda parts will work on them as well. (i'v estimated my priceing based on uk prices but if im wrong i suspect they can be had for less not more.)

Good Sunday my fellow Mustonians! Cup of Joe and ear pods ready!

Mustie i found your channel back when you first started working on the econoline, which i was hopeing you would get back on.what ever you do i always enjoy , you never disapoint,its always an exciting challange for you.

You mentioned about a fuel tank, a keg on the back of the dune buggy. Heineken sells about a half gallon keg shaped container of beer!! 😊

That little meyers manx buggy is looking great and probably deserves the engine rebuild. I love watching your vids. All that work deserves to have a chance at lasting at least a few trips into the sand pits.

UK first, surely!! I'm just waiting with a cup of tea and a crumpet for this to come through - makes my Sunday complete 😊

Thanks for the shop time Mustie1! Look forward to the engine solution and the completion of the project!

The clanking sound is loud, a good idea to find a backup engine. I like how you created the S curve for the carburetor. Awesome video Mustie1 👍

Looking at the governor set up, it is extremely similar to a generator. They have a centrifugal governor and as the engine speeds up, it closes the throttle. When it slows down because a load has been applied, the throttle opens to give it more gas and air. I think you should just run this one till it dies. If you are stuck with the form factor of the engine, you can just keep going on the build and then use it till another engine shows up.

I worked for a lawn service once that only put used motor oil in the mowers and trimmers. He would have us pour the oil after a oil change on the trucks into a couple 50 gallon drums and he bought used oil from small shops. He had us only add oil seldom change it. You could never tell by the look of the oil if something was wrong because it was mixed, it went against everything I was taught. That oil that came out of that reminded me of that horrible job.

When you're bending pipe that might kink, you can fill the pipe with sand pretty tight and seal it up to help stop the pipe from collapsing

Hey Mustie. Where you commented about pulling the starter cord out a bit so that the handle stopped clear of the carburettor, akin to how it is often on lawnmowers. Well how about doing it the same as that many ultralight aircraft? They extend the cord so that, using pulleys as needed, it is led around to place that handle in the cockpit. Thus the engine can be started from the drivers seat. Thus when the engine stalls, as it will inevitably happen occasionally, you don't have to climb out to restart it.

The larger Honda clones like that have a valve adjustment of 6 and 8 intake exhaust you can test the carburetors while they're off the machine with a mightyvac and should hold 7 PSI with the carb upside down. I used to be a small engine mechanic. Love your videos

I find it quite easy to use two nuts that you screw against each other to get pin-bolts out... Just a tip. Love your videos, keep em coming!

MIlwaukee will fix that drill for you if it's less than 5 years old. If that's the case just go online to their website and open a ticket, put in the serial number and they will let you print a packing label, ship it out ot them, they'll rebuild the guts and possibly give you a new outside (they saved my chuck and something else, motor probably it was brushless but replaced EVERYTHING else) anyway.. yeah man, you paid for it AND they give a 5 year NO QUESTIONS warranty.. DO IT man.. it'll be like 2 weeks, you'll come to the shop one day and there will be a Milwaukee box on your step. That was a good day!!

As always, never disappoint. An interesting turn of events but never the end. Keep up the good work! Blessings and respect!

That was a pretty cool way of visualizing valve float when you were revving it with your hand over the front of the carb to adjust the air fuel ratio.

I say toss it together and ride it till it blows up since it's already a write off. Also your intake for sure needs a support, carb is vibrating too much and cause fuel foaming.

Yes! Loving this one. I do this kind of stuff with my 6 year old Grandson, and this is right up my alley. 🤘 Edit: Pro tip! If you fill the pipe (any metal tubing) with sand, you can bend it without heat and it'll never kink or crimp. Looks like someone ran it for way too long on the break-in oil and ruined it. I've seen it 100 times. I'd crack the case open and put new bearings in it.

I never had a reason to relocate a carburetor. And the reality is I didn't know you could locate one so far and below the original position. First time I have ever seen it done.

Outstanding and awesome as always.Thanks for sharing and taking us along

When you got it running early in the video, I was amazed by the amount of smoke coming out. Seemed like it was way too much. Gotta wonder if it was ever broken in properly.

You have sense of humour and humility, so beautiful and inspiring ..

I've run into a few engines like that with very soft cam lobes. New cam shaft and your good to go. The end plate is sitting right there, you don't even have to take it out of the frame. Thanks for the video, information and detail is what I like.

Each video of yours I learn a lot, but I have to say I have never seen a carb set up like that before lol. It's a brave new world yep new world!!

Good.job Nice job cool Mini VW 😄👍👍👏👏👏

Good Morning Mr. Mustie! Thanks for starting off my Sunday morning!

Guess I'll have to dig out my own go cart if I want to see one running. lol Sick thing is, I have one @67yrs. old. Hope this weather holds out in Louisiana. Good luck on the engine.

Put a new rod in it while you can and save it. I bet oil was thinned with gas and that may have the contributor to knock. Good videos and I’m recovering from surgery so your helping me out !

Could you for the carb, done kind an L shape and had it face straight back, then it wouldn’t be right behind the rear tire and you could make an awesome air cleaner with plenty of room. Just a suggestion. You do an amazing job, love watching all of you stuff. I have been a Mustie fan for a long time. Keep wrenching!!

60 years ago my father taught me some of the skills you exhibit he was a stoker in the Royal Navy an when he left was a turbine driver at a power station I never asked who he learned from , watching you makes me wonder and as he’s been gone 30 years somewhat sad but also thankful for that apprenticeship he gave me

Sure would be great to see you execute a budget overhaul of that engine. What would you do to it if you had almost no budget? Not the practical thing to do, but it sure would make a great video;

Gotta love your ability to adapt what would otherwise be junk parts! Last year I built an intake out of bicycle forks for a similar carb set up on a flat head briggs old school mini bike build I did. Took some trial and error, but I think it looks a TON better than the generic bolt on ones, plus those didn't fit my application.

Right on time! Going by the title sounds like its going to be a rough one this week.

Yep has all the hallmarks of being started without oil from new, well that's a bugger. Safe travels. Ken.

Thar she blows L o L That motor has had the biscuit !!! 😊😊😊 🎄🎄🎄

i like what you do on KZfaq keep up the good work you do thanks.❤😂😮😊❤

Me, I'm grabbing a harbor freight electric start engine, locating the start to the front. You ad in I'm not getting any younger, jumping in and out of a fiberglass body every time it dies. No thanks...😮 PLUS the aftermarket support for the harbor freight engines are great.

Seems an engine rebuild might be on the horizon. Thanks for the good videos.

Shame about that engine. It looked waaaaay better than some I’ve seen. The Predator engine may be a good choice. I’ve used those and had pretty good luck.

those old VW pipes made a certain chirp sound that sounded neat

Unfortunately when these small engines go bad, they do it in a hurry. They are throw-away items. I have a nice older 9HP vertical engine with 110 volt starter I would donate to the cause. It came off a Craftsman snow blower…. I am sort of local Worcester Ma…. If you can use it for your project…. I will donate it…..

"She's dead, Jim."

Hey Mustie. Another great video. I say you tear it down, see what the situation is and go from there. We're all curious. Maybe you can even repair for cheap. Keep it up!!!

The ✨Forbidden Glitter ✨ ... 😱

So close. Nice job with the fab on intake. Wow! Impressed with the creativity

This channel makes me nostalgic for Junkyard Wars/Scrapheap Challenge.

Thanks, Darren! Enjoyed the video.

SW France....in the bath with glass of red wine

ALWAYS GOOD CONTENT AND KEEPING YOUR SENSE OF HUMOR!!!

You have got some stash doc brown mint content as usual love the videos keep on wrenching mate

Hay watching from London, UK 🇬🇧

I remember years ago my older brother bought a new lawn mower and he called me saying he only used it twice and it just quit. I went over and before I even looked at it he said it's a nice lawn mower it even came with a free oil change! My eyes got big! I instantly knew and was like oh man!!! they can't ship a engine with oil in it!!! That was supposed to be put in! He blew it up. Luckily they replaced it.

We want skid steer mustie!

As soon as I saw “champion” on the side I knew it wasn’t long for this world.

Yeah....step one, check the oil! Hope you find something. Love seeing you fix/build things, but seeing you rip it around is the best!

I have worked on a number of Champion generators with that Honda clone engine. They all had one problem. The intake valve would carbon up around the valve stem. this added resistance would cause excessive smoke as the valve didn't fully seat, similar to bad valve guides they also sounded like the bottom end was ready to go. while not a permanent fix, polishing the stem and valve guides extended the life of these engines.

Excellent video Mustie 1 :) think was low on engine oil also didn't change break in Oil on when should been changed and very low in crankcase so bearings inside got worn out need new plus exhaust also intake didn't get adjusted in time ! Also see if find Briggs & Stratton motor 13.5 hp 500 CC snowblower motor to it has electric start by house extension cord too and you may want try ! Also you did best too could!

When I worked at Canadian Tire, ICE powered machines, splitters, generators, etc, were prone to return within 1 or 2 days of the weather event they were needed for. In Canada, those machines are NOT shipped with oil in the engine. There are 47 warning stickers on them from the outside of the box to the ripcord handle. But some people just make the incorrect assumption that the store has already taken care of putting oil in the machine that they just removed from an unopened box. Anyway Mustie, rip it open and show us her guts. We can take it. We've already gone through so much. We'll need closure. Cheers.

I always think Mustie1 must have a dozen engines lying around that he could drop in a go-cart like this.

If it was mine, I'd pull it apart and check to see what's damaged, what can be repaired, and what new parts are needed. My guess for a budget repair... use muriatic acid to get the aluminum transfer off the crank and give it a light buff with 1000 grit. Put in a new connecting rod, hone the cylinder, maybe a set of rings and lap the valves. This all assumes that the parts are available. Then I'd check that cost vs. a new/good used engine.

I love your laugh. Greetings from Tokyo. I used to live in Laconia NH

Nothing better than sitting down to supper and watching a mustie so relaxing 😃

Great video, looks thanks for sharing

That's unfortunate. Hope you will find a good running, well fitting engine. Best regards, luck and health in particular.

Great vid, thanks & hope you get another motor.

Great video as always Mustie.

I’ve used copper pipe as an intake on the go car before it works great you get a lot of power because as the air is getting drawn through it, cools the pipe. Eventually the pipe will freeze over and get a nice cold charge of air straight into your engine.

Awsome ingenuity on the build, but a grumpy engine. Would be nice to see a teardown on this one. 😮

Mustie1, Sorry that engine didn’t work out. All the other stuff you did to the dune buggy are great! So I’m glad you're just gonna get another engine for it. Yea, a teardown of the old one would be interesting, plus you never know, you might be able to put new bushings in it?
