I'm 61, been working on small engines all my life. Owned a couple Onans but never worked on them other than changing oil and plugs. I feel like I'm back in shop class in school learning, listening and absorbing all this information, and may I add from an excellent teacher.

you are one of the better youtubers in my opinion. i dont hear like and subscribe from you every 2 seconds (although that would make a funny imitation). your wholesome and you teach stuff i can use. not like other youtubers that say something needs a fix and than turns the camera off. thank you

As usual just going to bed in Australia, but now I can sleep easy tonight after worrying about those lost Valve Caps all week!

Nice work straightening the valve stem. I appreciate you showing us “real world” fixes instead of just throwing money at it and buying new parts. Thanks for sharing your knowledge and time.

Take this restoration all the way mustie they dont build machines likes this anymore and its a beautiful tractor. Plus you have the attachments for it to restore, please fix it all up it deserves it. Thank you for your hardwork sir.

Your knowledge is impeccable. Love watching and learning from your vids. Cant say enough about how good you are.

What started out as basically an inspection turned into a deep service... Sounds a lot better does that...🇬🇧👍

I was a little sad when you moved into your new shop, now a few weeks later, I'm already fully acclimatised. A good lesson to not get too attached to things that are not important.

That engine sounds really smooth now. You have a really good way of explaining issues with a broken or out of adjustment part. You have good teaching skills.

It's always a pleasure watching you overcome problems, and you calm demeanor is... well, um... calming. Thanks for the video!

What you were describing to do with the valve seats is called staking the seats. Something us old timers did a lot, to retain the seats in position. That Deere is going to be like new, when you finish! Great content, Darren, you're the only channel in this category that I subscribe to.

Mustie1, I wanted to let you know that watching your videos is one of the main things that calms me down nowadays when I have stress in my life. Thanks for that.

“Let’s just clean it up and see if we can get it running”. Well that went off the rails pretty severely lol

Your an inspiration to all backyard hobbyist (and techs also). I work on all my equipment and your constantly teaching me things I never thought of before. don't ever stop, keep fixing, keep taping, make them as long as you need !!!

OUTSTANDING!!!!!!!!!!! Fun times in Mustie1's Garage!!!!!!!! Brings back old memories. Can't wait for the snow plow resurrection! Chains and a cab! Yeah, a cab! Build a cab to keep your feet and hands warm.

Most likely you won't see this comment, but I just wan't to thank you for inspiring me to get back into repairing old lawn tractors. I had a lot of fun today showing my 6 year old grandson some of the old Sears Suburban tractors I've brought back to life. Thanks for the great videos, I always learn something new!

Nice way to start my Sunday. A cup of coffee, a couple eggs, some bacon and toast, and a new Mustie video. Thanks for these always a pleasure to watch and perhaps learn something.

Welcome to the wonderful world of Onan. Sold to McGraw Edison around 1970 and then to Cummins. Your engine is either a B43 or B48, both based off the CCk series. I've worked on too many Onans to count. Yes, parts are getting scarce and $$$$ and will only get worse as times go by. The CCK series is mostly indestructible as they have cast iron blocks and a far better bearing system than the B40-series. B&S twins and these B-series engines share the same flaws, poor cooling flow and overheating. The B&S are worse with popping valve seats and after literally half a dozen tries punching in seats, we finally said "Uncle" and installed a Vanguard on a Woods zero turn. What great series and your explanations are clear and concise and top for YT.

I admire your persistence...running into unexpected problem after problem and doing the right thing by fixing it...also you take it mostly in a light-hearted way (at least on camera...LOL) You're also adept at when to take a few steps back to assess and take a break to try it again later...I know there must be situations when time isn't on your side but still handle it pretty well...all these attributes I see and the versatility you possess to work on anything and everything will always bring me back to your educational videos....along with your good nature, knowledge, and modesty to share with others what you know...keep up the good work!

I've been watching this channel religiously lately, my father in law is paraplegic and to get him out and doing stuff we fix up any old mowers and trimmers this channel has helped me a lot cheers mate

This series on the 318 has been one of your best, if not thee best. Can’t wait to see her fully assembled. Thanks, as always, for your time and effort in creating another excellent video.

Way more than I could have don in the back yard it is really grate to see it running so good glade I gave to you have done it right Dan

My dad was a master armourer in the Canadian Army, one of his long serving armourers could straighten a bent gun barrel with wooden mallet and a few jigs that he made himself. For 3 weeks before hunting season all he did was true up guns..

what makes Mustie unique is when he applies a fix to a perplexing problem that most of us would struggle or give up on....and makes it look so simple in the end...amazing..one of the best i have ever known or watched..

Love Sunday morning shop class with Mustie1. Thanks for the lessons complete with precision hammer taps.

Onan was bought by Cummins. I work for them as a diesel mechanic and we sell many old onan parts. Some for this engine too. Go to your local Cummins branch and you should be able to get something

Excellent series on the John Deere. I'm past the age of tinkering on engines, but I sure wish your channel had been around when I was. Very educational and your never fail to teach me something new.

Wouldn't be a complete Sunday morning without a Mustie1 video. Great job on this one. It's one thing to rebuild a Brigs or something that you can just order a slew of brand new replacement parts for but an entirely different thing to have to make due with what you have and have to repair or refurbish the parts you have because replacements are not an option. That's what makes the difference between a true master and just a parts changer.

Rewarded for your patience and thorough checkup on this engine, sounds great! What a way to balance a serene New Hampshire scene with an Old Man Puttering sign. Another best!!

Cracking job my friend, sounds sweet. Can't wait to see it all back together again, then the refurbishment of the plough before the final assembly. Brilliant video, best channel on KZfaq.

Very nicely done Mustie. I admire your persistence and thoroughness. Thanks for sharing. Nice plow with the controls, so nice. Hoping you play with the snow blower as well.

Love the old Onan engines. We used them for garden tractor pulling for years. They have a distinctive sound to them.

Excellent video, getting into and correcting the valve train problems was educational and informative. Your videos are the best!

Pat on the back time Mustie , another superb save from one of the best you tubers around , thanks for the great content she's purring nicely now!!

AWESOME ! Tip - the witness mark from the lapping process is all that's needed for determining contact on the valves - no marker required. I've been porting and rebuilding heads for 25 years. : )

Thank you Mustie, for the pleasant relief you provide from the constant deluge of political and social storm front. Im in central florida, and right now we're waiting for hurricane Dorian to decide if it's going to kick our but t, or give us a pass. You provide a wonderful distraction, full of humor, useful info, and relaxing mechanical problem solving. Thank you for providing a stress free "safe place"! Congrats on the new digs, I am a subscriber, and happy to be so!

Mustie, You put a lot of hard work into these old machines and in the end you have a nice usable piece of equipment. AWESOME!

Quite simply THE best. Mustie1 has no equal. Loved his garage at home but that new place .......wow !

Every machine tells a story of its past treatment and thanks to your repairs its story didn't have to end here!

Reminisce when I was in high school 1981 in small engine class. I wanted to be an auto mechanic or diesel tech. Thank you. you bring back old memories that we all miss. Only work on Bridges Stratton 3.5 hp tearing down put back together over & over.

Sounds real sweet. A job well done! Love the clockwork camper at the end - made me smile.

That has to be one of the smoothest 2cyl engines that I've heard yet. Seriously some next level stuff Mustie. Thanks for postin'!

The valve guide demonstration was very helpful, I wouldn't call it a rant. I've been working on stuff my whole life, and I learn something from all of your videos.

The JD 318 was a beast of a machine / mower. Had one for years! Sold it to buy a JD 455 I've had it the last 20 odd year. O and I agree with the others here,You are Excellent at what you do. I've learned many things from you over the years watching you on here. Thank You!

I've had a 22 hp Briggs and Stratton OHV seize the intake valves at start up after I used old gas that was stored in a metal gas can. Engine ran fine until I tried starting after it had cooled down. Varnish built up around the intake valve guide which held the valve in place. This bent the intake pushrod on one cylinder. Much effort was required to free the valve so it had easy movement. Wonder if something similar happened on your engine? Your engine doesn't use pushrods but restricted valve movement may have contributed to cap falling off.

She definitely sounds much better without all of the valve noise! Great job!

Nice work! It's really purring now! I cooked my John Deere mower several years ago. Was almost finished mowing and it came to a halt after about five seconds of horrible screeching. I opened the lid and found the screen on top of the engine completely clogged with cottonwood fuzz, which had been flying around in copious quantities all day. Lesson learned, the hard way of course.

Those old Onan engines are hard to kill, kinda like the old cast iron Kohlers that I love so much. My uncle recently had me go through the 318 that he bought brand new. He's used and abused it for 30 years or better. It's his lawn mower, roto tiller and snow blower. Other than normal maintenance, the only things it needed were a carb rebuild and a few cracks in the deck welded. He was thinking about buying a new tractor, but, can't be happier now that the "mean green mowin machine" is running, mowing and tilling properly again. My 70+ year old uncle is also looking forward to winter...he can't wait to get into his Carharrts and do battle with the snow (after his 51 year old nephew installs the snowblower and tire chains of course) lol!

Hey Mustie1, you got space for a little paint booth in your new digs? Lookin at all those Deere skins, it might be handy. As always, great vid.🤙🤘🤙

Nothing to add to all the positive comments below, but just in case it matters for the "ratings algorithm," throwing you some good vibes. Great as always.

That valve tip thing happened to a 16 horse Onan on my Miller welder. Went down to the crankcase. That’s how I knew that was your problem. It’s all fixed up now. Unfortunately, I also have a 20 horse Onan that I want to use for a log splitter. I’m not looking forward to tearing into that one. I love Onan motors but I hate working on ‘em. Great video.

In my dad’s old .hip roof’ tool box there is an old hand crank style valve lapper, kind of like an old hand drill driver but with a suction cup instead of a chuck where a drill bit would mount. When cranked, it would rotate the valve back and forth, advancing the rotation incrementally . So instead of running the stick with suction cup between your hands, you would just crank the ‘drill’ handle and lift it up occasionally to help spread the compound. Old school stuff. Love this channel.

You are great actor, I almost 😉 believed that engine was heavy.

Outstanding, as always. Just think, in three months, you’re gonna need that plow!

Wow, she sounds so much better. Nice job with the cleaning and repaint while waiting for your gaskets. Looking forward to seeing and hearing her run and cut some grass and to see how the other attachments work out for it. Knowing you those will probably get a new paint job as well.

Great work, it'll make a great tractor for you. Those old John Deere's were great. There's a reason when you find them that they fetch a pretty good price, they're built to actually last not fall apart after the first season like today's box store junk.

Damnit Man! I bruised a finger on the edge of my desk providing the drum roll & you didn't even hear it!

Using your lathe and an indicator you could have got that valve near perfect. We straighten shafts all the time that way. .001 or better. Best vids on the web. I love the vw content. 65 was my first car.

This kind of backyard mechanicing I haven't seen in years, the one with a man a blow lamp and a hammer, fixing stuff.. the straightening of the valve stem and the compound on the valves, one of the things my dad, and my next door neighbor (he had an ancient petrol mower) used to get me to do as a kid.. (it teaches you patience, if nothing else)..

The man said drum roll please! Ok....that’s better. Aaaaaaaaand the crowd goes WILD, nope nope. The crowd nods in expectant approval of another failing machine revived at the masterful hands of Mustie. You’re an inspiration. Your videos are fun, extremely educational, and now all I do is comb classifieds looking for castoffs wanting to emulate what you do.

Hmm, a conversion to a two-cylinder diesel would have been awesome, but seeing this engine run again, that's just as good, love me an opposed-twin engine... :D

nice work Mustie...she's gonna be a good snow pusher

The old man puttering sign at the end is priceless....made me smile, great videos keep me coming!

I think I've watched every video you have ever released and so far I have not found a single video boring, your funny, explain everything in easy to understand as you go along explaining each step you are performing, and the reasons why you are doing what your doing, I look forward to your next video M@x

you should contact norman from i save tractors. they are making all sorts of parts for the onan engine. 👍

"Old men watching old man puttering".... I hope if I ever need a "straightened" heart valve the surgeon watched this video, no loctite though, please, not FDA approved!

Hi Darren. I really enjoy seeing how you recycle/reuse and save the old parts - valve.. I had to give you a quick smile today.... I purchased an ingersoll 4020PS back in the 90"s Went to a local bar early in to have an after noon snack with a friend. Come to find out his friend was an engineer for them. Told him I had a foot control for the speed control. Not on the handle. Life is so cool, amazing on what every one does!

The iron duke does it again. Great job you give some of these young guys an incentive to want to be a good mechanic and builder. Keep at it mustie Thumbs up...

WOW! Sounds really nice now. Great work!

Thank you for the magnetism update!

Hey Mr M, I freely admit to being addicted to your channel, it's excellent! Dustin Hoffman in "Rain Man" said "I'm an exceelent driver", You sir are an excellent tutor. Many thanks for sharing, from an old Yorkshire "Geezer" in Ireland.

We had a 318 at work and several other things with Onan engines. Onans were cold blooded hard starters. The choke had to be left on for a long time then guys would forget to open the choke and the pistons would carbon up. The valves were constantly coming loose. I used to screw the adjusters out as far as I could, pushing the valve open, then use a punch to flatten the thread before screwing them back in to adjust the valves. It seemed to cure the problems. I've never seen a valve bend at the lifter end like that.

Love your videos man! Best humor, best kinda work, best fun!

Well done! I love how excited you get when it works, lol.

I can’t wait until every Sunday to sit down and watch a Mustie1 video with a hot cup of coffee , I love all your videos they are like a bubble bath for your brain

THANKS FOR THE CLASS Mustie, YOUR A GREAT teacher. Yeah I would have pulled the valves for clean up.

I would've loved to watch you clean and paint this mower!

That sounds amazing now! What a difference hey. It's a unique sounding engine that's for sure - sounds so much nicer than a Briggs V-twin I recon!

When I worked at the mower shop, we had to peen the exhaust valve seats on all of the new Briggs-powered mowers, before they were sold, because they would come out. Love your videos-thanks!

A long time since I last seen someone grinding valves! I remember watching my dad teach my brother this skill years before his apprenticeship with ford. A skill no doubt invaluable in his progress to him becoming a master technician all these years later.

Great video. Love to see you fixing stuff. but think a moment about your back and get a little crane or something to get those engines in and out.

I do like the nature shots at the end. Just for grins, do you have any shots of a stream in the winter and same stream in the summer for a comparison? Glad you got the engine diagnosed and fixed. Sounds very good now. Dave.

i so appreciate watching when something goes wrong, and seeing how you fix it. That's what we all run into -nice to hear your thinking, when that happens.

Great video! Hope you take a break to enjoy the jet ski you fixed last year.

37:38 Regular extensions or rated torque sticks have no effect on the final torque delivered by a hand held click or beam type torque wrench. They only limit the torque of powered impact tools.

Using an extension on a torque wrench (no matter how long) does NOT affect the output torque. The torque you put in equals the torque coming out the other end. You will have to rotate the wrench further because of the elasticity of the metal, but as long as pressure is held for more than a very brief amount of time, the same torque comes out the other end. This does not apply to impact wrenches as they do not apply constant pressure.

I really admire your patience and attention to detail. My Dad drilled "attention to detail" in my head to the point where I'm almost obsessive.

Good series. This gave me a lot more respect for John Deere lawn tractors. That's a solid machine.

Hi Darren, great job as usual ,is your camera slightly out of focus , or maybe my tired old eyes? All the best from Scotland , and keep up the great work!

You got a drum roll from both my 9 yo son and myself. He even threw in some cymbals.

So glad you have the knowlege and the drive to teach us. And don't forget the funny comments i know you just want to see if we are paying attention.

Thanks for the indepth video, tapping the valves back straight, and putting the home made screen in . Tips I can definitely use. Keep up the good work

like a kitten and you managed to keep the red fluid from spilling, I got 2 band aids on from just watching the vid :)

10 minutes and a full page of comments....are we interested?!?!?!

Fantastic Sunday with you Mustie1, thanks for all the great tips and bringing us along!

Living the dream I'm almost halfway through all your videos I love tinkering working and fixing Motors / engines I am a mechanical maintenance technician and what you do is what I'm working towards it would be at home on my own hours doing what I love to do

I really have to wonder why anyone would thumbs down a Mustie 1 video?

I've been waiting all night for this video! Time to make the Donuts!

Thank you sir for letting us hang out with you in your new shop! Looking forward to the next video and of course a proper test drive in some really high grass. "Nothing runs like a deere"... Greetings from a cold and rainy northern Sweden! //Daniel - Kalix, Sweden :)

After you assembled and started, that engine sounded so good. I never knew that when lapping valves (into their seats) the sound changes. Talan Peterson makes a good point. Persevering in tracking those valve caps was a relief for me as well........ Happy endings do work ! Thank you for the videos and teaching us.
