Mustie, keep your videos exactly like the are, you educate more than entertain. Most of us want to learn not be entertained. Your commentary is the entertainment :-) .

Hey Darren, we all hang out for your vids. Most of us would like it if you'd keep it as it is. We need no 'excitement music' during the time lapse stuff, silence is totally cool. There's so many like me, we have a shed , we have money but we don't have with what we Aussie's call 'a mate do to do shit with ' . You make our world better.

My wife says " You fix stuff all day at work. Why do you come home and watch other people fix stuff?". Lol. Have to watch mustie1. Great videos!

Let's go, must say you're my favorite youtuber and I'm 19 and certified in Motorcycle marine powersports but I've learned way more from watching you than I did from my 11-12th grade tech school teacher lol. Now I fix and sell mowers, four wheelers etc. Now to watch this amazing episode! Make sure you guys like and subscribe to the best youtuber ever!!

I think what I love most about watching is that all my uncle's and Mom can all turn a wrench. Most of my uncle's ran or owned a garage back when they where gas station and garages all in one. They always said you don't make any money selling fuel. The gas just made it easier to find you. They, like you could make an engine out of a tin can some water line and the bolts holding the TV antenna to the house. Thanks for letting us watch you. It's really great!

My mid 70s Rupp Roadster had a “torque converter” that looked like the one on the Beaver. I think you are correct that the rear pulley is correct but the one on the engine is not the original. Also, when you use taps with a drill driver, my machinist father and grandfather turn in their graves. 🙀

Just discovered you. I'm 67 and boy does this bring back memories! SUBSCRIBED!

My friend Bill is the largest Rupp dealer in the country. He bought out all the old shops that was in business back in the day and had the parts laying around and doing nothing with them. He races Rupp snowmobiles and is his main thing but he definitely has some strange looking Rupps. Probably lots of parts

Also, disassemble the comet clutch and spray graphite dry lube on the internal weights, the sliding hub and on the ID of the brass bushing. Love watching this guy

I have always enjoyed your channel, learned some, vicariously lived through you a bit, but this Rupp mini bike has really touched my heart, I had a 5hp model in the early 1980s that I put uncounted miles on in my rural area, thank you for bringing back my fond memories of a simpler time.

I love your videos! It's like watching a master class in bodging. There used to be a show on Discovery Network call Junkyard Wars. You are like a personal visit into junkyard wars. I love the way you talk us through what you're doing. Almost as good as being there.

Thank you for explaining how things work in your videos.

Hooray mustie1 new vid,my hubby has got me hooked,I always help him with his classic,hope wifey n lady ok.👏👏👏👏🐕🐕🐕🐕

90 minutes of Mustie on a Sunday morning. I’m gonna need another cup of coffee. Can’t wait.

Another great video! Thank you for all you have taught me. My dad was an automotive and aerospace engineer, not a tinkerer, so your videos are a special treat for me. My friends now ask me to help them fix their mowers, leaf blowers, etc.

Great video Mr Mustie1. When you're looking for parts the saying "Can't see the woods for the trees" springs to mind.

Hey Mustie, Just a fyi - the carb you are taking apart is a Tecumseh diaphram carb. The orientation of whether the gasket or the diaphragm goes first is dictated by a stamping of 'F' on the carb. If the carb has an 'F' stamped into it, the diaphram should go first, otherwise the gasket goes first. Also, that seat you were missing should be the same as the seat used in all Tecumseh carbs. Cheers,

I picture Mustie's stash collection when he comes calling for the one lucky piece..."You have been chosen!!!" Love the content and always makes Sunday morning fun

This governor setup on the white Briggs is ingenious

Thanks Mustie - I like this format. There is not only technical education but also real world practicality and perseverance. Your personality is the lubrication.

The back pulley halves have holes in them for those spring ends to go into. The inside half has three holes to set spring preload for flat terrain, the next hole is for slight hills and the third is for extreme hilly conditions. The outside half has one hole ,so you put spring end into hole and twist it to preload it. According to which hole you choose on the inside half determines the amount of preload you get.

The sunday this was uploaded (i'm posting the day after at after midnight) was my birthday, and I am so happy to say that mustie was my inspiration to fixing small engines and follow through on my interests in how stuff works. A few weeks after my first video i watched (the push mower with the no change oil and the upside down blade) I picked a lawn mower from my neighbor's trash, they were throwing it away and i was like "you know what, I can fix that for sure" I asked them what happened and all they knew was that it started revving full speed and they stopped using it. I tear into it, find the carb had been roached by ethanol, and that the self propel had ceased up from sitting, which i had to pull the motor off to get it out, and fixed that. then when i was putting it back together i found out they had managed to drop the governor rod and thats what caused the rev issue, which led to the problems from sitting. It's a beast of a mower now, a honda hrr216 that i got the side discharge chute for which allows me to get in narrower places than my briggs powered bolens because the side chute doesnt stick out. I wouldn't have taken that project on had i not started watching mustie and i thank him, because not only did it prove to me i was capable mechanically to fix things, it saved a otherwise perfect machine from going to the landfill.

"land of the lost" fights back if you want to take up one of their buddies. I love this series!!!!!

I am addicted to this video, as my wife’s maiden name is “Ruppe”. ;). Gottscheer German name. My dad-in-law, who I loved almost more than my own dad, was great at fabricating just about anything, whether for plumbing, electric, motor, just about anything. I can see why the “Rupp” name is on that mini bike.

You might find it's tricky dealing with your oil without a filler on the right side of the block. Also, Rupp Tecumseh engines had an extra tab on the rod to help splash oil around because of the angle that they sit. The serial numbers on them are marked with an HS35, HS40 or HS50, depending on horsepower.

I have always enjoyed watching mr mustie fix things my mom has always been irritated bye how much time I spend on KZfaq watching videos I just lost my mom November 20 th I haven’t been on KZfaq like I was it’s addicting honestly but I can’t resist me musties videos and will say he seems a truly good caring person and anyone fortunate enough to have him as a friend is blessed great video !

Me and my son Noah 6 years love watching you we send a big thank you from the Roberts family from England 🏴󠁧󠁢󠁥󠁮󠁧󠁿

Your mechanical skills and sense of humor are amazing

I had a spring-loaded screw get launched across my shop. I looked and looked and looked, finally had to order a new one. About six months later I opened my fire-proof cabinet and opened a locked drawer inside and found that screw sitting on top of a pile of papers. I guess there really is a Twilight Zone for that sort of thing.

Sunday morning with mustie brilliant, another one lives, can't wait to see it finished, respect from the uk, 😁👍

Ya made me nervous when that tap started fairly crooked I thought for sure we were getting a lesson on broken tap removed 😂

This was an interesting show..... thank you for taking me for a ride.

That spring on the rear pulley is suppose to be wound up some so that the rear pulley is torque sensitive. In other words as you apply power the engine rpm will go up. Adjusting the amount of wind up will change how much rpm changes with torque.

Another great video. Mustie in a throwaway society, it's refreshing to see someone who loves to resurrect old stuff from the dead or long hibernation. They should put together a curriculum to teach high school kids or even at the college level the things you do on your channel. It would be a valuable lesson and save a lot of money for those who would do some of the things you do. I especially love "the stash" of stuff you have just in case you need it. I think even Fred Sanford approves of your hoard of junk parts.

Mustie, my brother Gary and I are longtime fans of your channel mainly because of the wide range of projects that you tackle. Keep up the great work! Congrats on your 610,000 subs!

Finally someone who knows how to make there own gasket with a small hammer and gasket paper. I have been yelling at my t.v. for the last 2 years watching these young kids work on stuff that they could make 50% of the gasket they need themself and save some money. My grandfather showed me 65 years ago and I don't by gaskets unless it's a special kind. I buy gasket paper and cork of different thicknesses I have never had a problem with one of them. And have saved a lot of money. I thought of anybody on KZfaq you would be the one who knew how to. Your costom bikes are out of this world and your VWs are awesome 👌 👏 👍

Just realized been watching this for long time,just subscribed ,thanks for content Darren

I really enjoy your videos you’re always repairing something out of nothing I look forward to them every Sunday.

That darn pull start was stressing me out. I was yelling at the TV when you mentioned it was your next fix. Great video. I really enjoy watching you work through/solve the challenges.

This Rupp brings back a lot of memories of my Rupp Enduro and my childhood.

Mustie, you might want to put the moveable sheeve of the primary clutch on the outside rather than the inside. This would help with the belt alignment with the secondary clutch. This is how it’s done on snowmobiles!!

Ready for part 2

Learned how to cut a gasket with a ballpeen hammer never saw that trick 58 yrs old and very skilled still learning new tricks that’s what I love about your channel

You are an incredible mechanic, fabricator. Just wanted to thank you. I've been an auto tech for 13 years, with a terrible history with small engines. Now, I have had several mini bikes, pit bikes, tractors, that I've been able to get mint, with knowledge acquired from your videos. I appreciate you educational videos. Truly.

I had a Volvo 340 GLE with the Belt Drive Auto , A very efficient drive system ! Biggest Rubber Bands you'll ever see !!!

As far as your concern with the clutches moving opposite directions from each other, all Polaris ATVs and Side by Sides(possibly the snow mobiles as well, never dealt with them) have been setup like that for years and never a problem caused by it

I really enjoy watching you work on junk. This is my Sunday fun.

Thanks brother again I go to school every time I watch you man.

I think you have the clutch on backwards mustie. I have a Rupp roadster and the movable sheave is outside. Love your vids👍👍👍👍

Heck yes you Musty will get it running !

Thanks to your videos I was able to swap a worn out Briggs and Stratton engine on a old rotor tiller with a better Briggs. Your videos helped me disassemble the carburetor, clean, reassembled and adjust so it ran perfect . Thanks and please keep up the videos.

The mini-bike whisper. From a box of miscellaneous parts to a roller. Very impressive.

i had one of those years ago but it was missing the jackshaft parts, i was able to flip the rear wheel and run the chain directly from the back sprocket to a regular minibike clutch, i may have ran rear struts instead of shocks to keep the chain tension consistent i cant remember. I worked out good, it lined right up.

That was fun, can’t wait to see how it works under a load! You’re lucky to have a place to run one of those, all of the mini bike trails and woods we had when I was a kid are now rich peoples well established lawns.

Another enjoyable afternoon watching Dr. Frankenstein mastering his craft! Thanks Mustie!

Those clutches remind me of Harley riders with open primaries. It is nice to see you save that old Rupp. I had one similar to it back in the late 70's/early 80s.

ive done the exact same thing tapping the shaft and it seems like they're hardened on the outer but you drill a cm into it you can feel the shaft is softer

That looks like a Rupe roadster...I had the roadster as a kid. Took off that hookey torque converter setup (this is an early cvt .. they used these in some snow mobiles)and replaced it a centrifcal clutch and sprocket.

It LIVES....well sort of. You are getting that puppy dialed in nicely. Thanks for posting these videos.

My favorite Sunday morning coffee companion-love your show/school/adventures-thanks Darin!

GOOD MORNING !!

It looks like the secondary clutch needs flipped to match the front. I’ve never seen one ran opposite each other. And the spring needs a little preload to keep it from opening too soon.

Thank you for sharing. Mustie1 and Yellowstone tonight, what a great day!!

My dad taught me the ball-peen hammer/gasket making trick over 60 years ago. Thanks for the memories. Wishing you and yours a Very Merry Christmas.

Im pretty sure my Scooters clutches are setup the same as your Beaver too . I am wondering if the prev owner was cobbling stuff together too and gave up on it ? Just my 2 cents

I think that primary clutch is on backwards the dome is supposed to be on outside

Looks through his hoard of spare parts... "I don't wanna take a good one..." Mustie1, everbody! I love it, I would absolutely say the same thing!

I love the "something from nothing" videos, this is a great one, Thanks!

3:47 Using a carbide rotary file on a Dremel will work to deepen the key slot. 20:31 Guess you never worked on driven clutches for a snowmobile. 1:19:34 I thought he had a lathe. He could cut the driven clutch nut down for a better fit.

Knowing how to secure your financial well-being is one of the most important things you’ll ever need now. You don’t have to be a genius to do it. You just need to know a few basics, form a plan, and be ready to stick to it. No matter how much or little money you have, the important thing is to educate yourself about your opportunities

No kidding ,,Lucky ducky,,you got lots of stuff to keep going all winter long!!! Thanks for sharing Mr mustie!

Good morning, I a fairly recent subscriber to your channel, I have learned so much in the last few months, just wanted to say thank you, and keep up the great work. Sunday morning wouldn't be complete without Mustie. Take care my friend 👍

sorry I was in a hit-and-run accident 3yrs ago I'm having and hard time through it. and it's no fun. sorry . Jay The Florida pool pump motor bearing repair guy When Service Calls Longwood approved ! that was good info Mustie1👨‍🔧

I swear you do stuff backward just to make me crazy!

I had to smile when you opened the ultrasonic cleaner - that basket is SO ******** CLEAN !! It's very, very similar to my deep-fryer, which I do try to keep minty fresh; at thirty years old though, it doesn't look like that. Usually, anything that cleans, is pretty filthy itself - that ultrasonic must be the cleanest machine in the shop.😁👍

Rupp Sprint. Bought mine new, at 14 ,in 71, with money I earned. My world was complete! Now,at 65, got a few v twin cruisers, and a sweet Yamaha R1. A bit different than the mini bike!

i think you have the clutch on the engine backwards

Dude, I feel bad for whomever has to sell off your estate when you kick the bucket. It's literally going to be weekly estate/yard sale that will last for at least a year.

Excellent work, loved the way you showed the proper way to make a gasket, 👍🦘

I love this channel and Mustie , the only channel where we feel like we are in person with him in his shop just by the way he talks to us .. Amazing content 👌👌

Vroom vroom ruppp rupppp !!! Great job making the mechanical bits work!! You are a mechanical genius~!!

I do like the way you work like the A-Team making things work with bits about the workshop 😂

You are a very good teacher.

Orr! When you tinker with the small carburetor parts, it’s just like Orr in Catch-22!

That was a real session thing flying across the room a bit of laughter enjoyed it Mussti 😂👍🤠

Always entertaining to watch the master at work. It looks like you have more belts in-stock than many auto parts stores.

That's a great deal of dedication to a vintage basket case. It's more than I would want to take on at this time. I appreciate your efforts.

Silk purse out of a sows ear. Lookin good, enjoyed the progression.Thanks.

loving that gasket paper tip, thank you mustie!

Just to hear the sound of those 3 ponies brings back memories!! Love it!!!

My upmost respect goes to you with all the knowledge you share with us and the way you handled this bike in a box is amazing. Makes me strive to have a quarter of your knowledge / thought process in the shop. Great job and thank you as always!

Once again, very informative and educational, besides being super entertaining. It makes my day when I see the alert for a new video from you, thank you for the time and effort.

Longest video I can ever remember you making. Just fantastic! I love your content - keep up the solid work.

This I feel is the best video yet...I want more basket case builds ...plz

Its always awesome how you explain everything you do in the vids. I've used your expertise on a few of my projects and its helped tremendously having someone explain why/how things work. Another great vid Mustie1!

LOVE what you do!!! Keep up the awesome work.

I could watch a Mustie videos all day everyday. Always learning and always cool projects too

virginias husband, That style is a torque converter clutch. Very powerful, when adjusted right, you can climb walls with it! Had one 52 years ago when I was a kid! Lots of fun!!

The old stash comes through yet again. I am amazed at what you can bring back to life Sir.

Awesome she's coming togeather nicely good work Mustie!!
