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.
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!!
Man Caleb I think that is what US youtubers are all about......We dont want to die with all the knowledge and force the next gen to go through some costly school. I do the same thing with old cars and VWs.
I’m a lawyer. I come home and watch court cases because I don’t get to do that much at work. Learn a lot. Love watching Mustie1 too. Have lots of lawn and garden equipment and bicycles to maintain and keep running. I learn a lot from Mustie1 and he’s very entertaining. Can’t wait for Sundays.
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. 🙀
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
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 TH-cam you would be the one who knew how to. Your costom bikes are out of this world and your VWs are awesome 👌 👏 👍
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!
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.
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,
Those carbs are originally a Tillotson design. They were used frequently on those really old monster chainsaws that had the carb hanging off the back in the rear handle area. I had an old Sears that was built like that. Those carbs work fine at any angle, so there was no need to build a new manifold. The one it had would have worked perfectly fine. Also, the ring on the rubber seat always go down. The “pin” on the diaphragm should go toward the needle.
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.
What I remember from an old friend is that the Driven clutch spring not only offers expansion tension, but its torsion strength against the bevels is accounted for too.
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
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.
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 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.
I have always enjoyed watching mr mustie fix things my mom has always been irritated bye how much time I spend on TH-cam watching videos I just lost my mom November 20 th I haven’t been on TH-cam 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 !
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.
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
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.
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
Thanks Mustie - I like this format. There is not only technical education but also real world practicality and perseverance. Your personality is the lubrication.
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.
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.
Help lol I see the back pulley is touching both sides hows it going to open up to let the belt go down the 2 wages are touching I feel like it's backwards the other way would allow it to open up moving forward so the belt would set deeper. The way it is seem like the 2 halfs would move from the wages
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!!
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!
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.
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!
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.
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.
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 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.😁👍
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.
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.
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.
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.
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.
@@malbers35 hey ... I was 14 years old (I am now almost 60) but they sold those kits all over -- everyone replaced that stupid torque converter... the problem is the torque converters dont work well and were always a problem, very poor efficiency in these squish plate torque converters -- the latter Rupps used a more standard clutch --- but great memories.
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
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.
The first clutch moves the belt towards the bike, so does the second clutch. They look opposite as one is closing towards the bike frame, the second one is opening towards the bike frame.
@@urbex1789 I’m not sure most do, maybe the newer chinese ones but honda and every snowmobile I’ve ever ridden has them aligned with the moving side out on both clutches.
@@johntunstall9698, you are correct sir. The movable sheaves on the primary and secondary clutches must be on the same side. Most if not all current generation setups have the fixed sheaves on the inside!! Otherwise you’ll be torquing that belt and it will not last very long!!!
@@johntunstall9698 Just type "how a cvt work" on TH-cam and you find many videos that show it. Btw I'm mechanics and I open atv's and ssv cvt cases mostly every day so I'm pretty sure of what I'm talking about.
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👨🔧
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
Exactly, money is always eager and ready to work for anyone who is ready to employ it, I was able to withdraw my profit of $17,030 after investing $3,500 in just 14days of trading with Mr Chris Pulver
He has been able to secure a steady inflow of returns off my crypto , it's was a lost with this whole pandemic situation causing me my job, it's just amazing to find Chris Pulver and there's been no regrets ever since.
My Dad bought a Rupp Scrambler new in 1971. It was metalllic green with the "TC-1 Torque coverter" plastic cover over the clutch setup. The engine was a 3.5hp model, it had 10" wheels, big shocks and that thing would pop a wheelie with my Dad sitting at a stop at half throttle. I had a little 2.5hp mongrel mini bike pieced together from different parts and we would ride in the local sand pits. I got 50 cents a week allowance and could almost get 2 gals of gas with it. Its a crappy feeling running out of gas and having to wait until next week to ride. Thanks for the great vids.
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
The angle of the carb will change once the front tire is put on the rim.... I was trying to let you know before you tack welded it on but you couldn't hear me.. lol... love your work!!.. really good content.. I have a 2003 and 1986 CR250's I'm currently working on and watching you go through the motions of working out what could be wrong step by step has helped me out so many times.. so, thank you very much... CHEERS!!
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.
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!!
You have the patience of a saint with that pull start! I would have already parked that thing in the recycling bin on it's way to becoming a toaster. Glad you're saving a Rupp, I used to be envious of my friends who had these as I was growing up. God Bless and Good Wrenching!
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.
@@freetolook3727 Roadside pickup piles. Yep!! Although if I were in charge I'd say "search the garage and find what you want". Like an Ecology yard. And we will negotiate the payment on check out.
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 👌👌
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!
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 👍
Nice job sorting out the parts needed. Should be a sweet little rustoration when you're done😅. Can't wait to see the final results. Thanks for the invite to hang out while you turn some rusty nuts and bolts, Until part 3 ...have a good one.
I agree it never dawned on me that’s what you are doing watching your videos . Because I watch multiple videos from you over and over I think they way you just I feel like I’m there with you going over options it’s helped me on many other projects I appreciate your videos hard work.
Yeah Darren, like several people, I wouldn't use a tap with a cordless drill but; it worked out fine for you and that's the bottom line! Even with tap handle, I broke a couple of taps and "what a pain on the bottom end"!!! But love your videos and never miss them and ALWAYS looking forward for a new one! Keep up with such great doing friend! Best Regards!
1:18:22 You said you think it is screwing with you a few seconds before. I think maybe the bike or the carb was trying to save your life tbh. Love your videos, keep up the great work.
i don't know how i stayed for the whole show/not, another great start to my Sunday morning in fact it's the reason i get up excited each Sunday more so than football...txs for sharing(like and subscribed)
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!
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 :-) .
I agree to stay with the same format. Lots of TH-cam videos have too much overproduction, and "ass slapping" throughout the video. I love your videos.
Love it just the way they are. Great vids and commentary.
Agree 100% to Mick & everyone!
Don't change anything I'd say!
Mick, keep your comments to yourself. Most of us... you get it.
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.

By hand with power drill, not wise. Although done with a Bridgeport, much more accurate.
cordless tools have lots of uses but not as a tap threader.
Yes the original Tecumseh engine had the torque converter clutch on it that had four big tabs that came out whenever it was going faster
I was looking away from the tap like when I was a kid watching The Exorcist for the first time
The tap survived.
Just discovered you. I'm 67 and boy does this bring back memories! SUBSCRIBED!
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

Ah, it must have passed thru the legendary time/space wormhole to the parallel universe of lost frendle pins
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.
I think you have the clutch on backwards mustie. I have a Rupp roadster and the movable sheave is outside. Love your vids👍👍👍👍
Just about to say same thing .. front clutch on wrong way round ..
Right definitely on backwards
Your mechanical skills and sense of humor are amazing
I had a Volvo 340 GLE with the Belt Drive Auto , A very efficient drive system !
Biggest Rubber Bands you'll ever see !!!
I had a DAFF car made by Volvo Forward , Neutral and Reverse. Just a big Snowmobile Clutch.
No kidding ,,Lucky ducky,,you got lots of stuff to keep going all winter long!!! Thanks for sharing Mr mustie!
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 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.😁👍
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.
Like the cries save us from the storms waves but stay off my Private Beach 🏖️ .
Same here, really sad nowadays
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.
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.
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.
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.
So you lost all of your torque multiplication.... bad choice.
@@malbers35 hey ... I was 14 years old (I am now almost 60) but they sold those kits all over -- everyone replaced that stupid torque converter... the problem is the torque converters dont work well and were always a problem, very poor efficiency in these squish plate torque converters -- the latter Rupps used a more standard clutch --- but great memories.
My favorite Sunday morning coffee companion-love your show/school/adventures-thanks Darin!
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
This Rupp brings back a lot of memories of my Rupp Enduro and my childhood.
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.
most cvt's run in opposite direction
The first clutch moves the belt towards the bike, so does the second clutch. They look opposite as one is closing towards the bike frame, the second one is opening towards the bike frame.
@@urbex1789 I’m not sure most do, maybe the newer chinese ones but honda and every snowmobile I’ve ever ridden has them aligned with the moving side out on both clutches.
@@johntunstall9698, you are correct sir. The movable sheaves on the primary and secondary clutches must be on the same side. Most if not all current generation setups have the fixed sheaves on the inside!! Otherwise you’ll be torquing that belt and it will not last very long!!!
@@johntunstall9698 Just type "how a cvt work" on TH-cam and you find many videos that show it. Btw I'm mechanics and I open atv's and ssv cvt cases mostly every day so I'm pretty sure of what I'm talking about.
This was an interesting show..... thank you for taking me for a ride.
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👨🔧
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.
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
Poor people think about what they can buy with their money , Rich people think about what they can invest in with their money
Exactly, money is always eager and ready to work for anyone who is ready to employ it, I was able to withdraw my profit of $17,030 after investing $3,500 in just 14days of trading with Mr Chris Pulver
He has been able to secure a steady inflow of returns off my crypto , it's was a lost with this whole pandemic situation causing me my job, it's just amazing to find Chris Pulver and there's been no regrets ever since.
I've got steady return. Thanks to expert Chris Pulver. His profits is always assured. I've made £36,400 in just a month working with him.
So people stay out of investment or getting to try somethings new due to ignorance that's it
My Dad bought a Rupp Scrambler new in 1971. It was metalllic green with the "TC-1 Torque coverter" plastic cover over the clutch setup. The engine was a 3.5hp model, it had 10" wheels, big shocks and that thing would pop a wheelie with my Dad sitting at a stop at half throttle. I had a little 2.5hp mongrel mini bike pieced together from different parts and we would ride in the local sand pits. I got 50 cents a week allowance and could almost get 2 gals of gas with it. Its a crappy feeling running out of gas and having to wait until next week to ride. Thanks for the great vids.
Ready for part 2
Thank you for sharing. Mustie1 and Yellowstone tonight, what a great day!!
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
Ya made me nervous when that tap started fairly crooked
I thought for sure we were getting a lesson on broken tap removed 😂
Heck yes you Musty will get it running !
The angle of the carb will change once the front tire is put on the rim.... I was trying to let you know before you tack welded it on but you couldn't hear me.. lol... love your work!!.. really good content.. I have a 2003 and 1986 CR250's I'm currently working on and watching you go through the motions of working out what could be wrong step by step has helped me out so many times.. so, thank you very much... CHEERS!!
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.
It would be nice for him to find an old snowmobile to work on, maybe something unique.
@@gord7025 I always wanted a Manta, duel track, reverse and an in closed cockpit with heat.
RDF, I wish he would have kept the 5 HP engine on the Bike, Deepen the key slot as you said.
@@NoWr2Run I agree with you.
@@RichieCat4223 that would be an awesome machine. I've seen Raiders but I don't remember seeing one of them in my lifetime.
Excellent work, loved the way you showed the proper way to make a gasket, 👍🦘
GOOD MORNING !!
Vroom vroom ruppp rupppp !!! Great job making the mechanical bits work!! You are a mechanical genius~!!
I think that primary clutch is on backwards the dome is supposed to be on outside
Yes the clutch is on backwards
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!!
I swear you do stuff backward just to make me crazy!
i think you have the clutch on the engine backwards
You have the patience of a saint with that pull start! I would have already parked that thing in the recycling bin on it's way to becoming a toaster. Glad you're saving a Rupp, I used to be envious of my friends who had these as I was growing up. God Bless and Good Wrenching!
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.
@@freetolook3727 Roadside pickup piles. Yep!! Although if I were in charge I'd say "search the garage and find what you want". Like an Ecology yard. And we will negotiate the payment on check out.
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 👌👌
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!
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 👍
I really enjoy watching you work on junk. This is my Sunday fun.
Nice job sorting out the parts needed. Should be a sweet little rustoration when you're done😅. Can't wait to see the final results. Thanks for the invite to hang out while you turn some rusty nuts and bolts, Until part 3 ...have a good one.
Orr! When you tinker with the small carburetor parts, it’s just like Orr in Catch-22!
Always entertaining to watch the master at work. It looks like you have more belts in-stock than many auto parts stores.
I agree it never dawned on me that’s what you are doing watching your videos . Because I watch multiple videos from you over and over I think they way you just I feel like I’m there with you going over options it’s helped me on many other projects I appreciate your videos hard work.
I appreciate that
Absolutely outstanding. Class act thank you. Regards Gareth Wiltshire UK. Gratitude. Quality. Respect.
Enjoyed the video. Made me want to dig out my Rupp and try to get it running . Thanks for sharing
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.
Yeah Darren, like several people, I wouldn't use a tap with a cordless drill but; it worked out fine for you and that's the bottom line! Even with tap handle, I broke a couple of taps and "what a pain on the bottom end"!!! But love your videos and never miss them and ALWAYS looking forward for a new one! Keep up with such great doing friend! Best Regards!
Brother love your knowledge and laughter
Love all your videos, thank you for takes us along. God bless and merry Christmas
The old stash comes through yet again. I am amazed at what you can bring back to life Sir.
Longest video I can ever remember you making. Just fantastic! I love your content - keep up the solid work.
1:18:22 You said you think it is screwing with you a few seconds before. I think maybe the bike or the carb was trying to save your life tbh.
Love your videos, keep up the great work.
Been subbed for over 4 years, Congrats on over 500k. Absolutely wild!
Great project Mustie1! Love the fabrication of items to fit the needs...helps having a nice stash like yours 😁!!
Awesome job mustie. Always enjoy watchin your projects
Great job love the snow blower carb can't wait to see it on trail in back yard thank you for sharing and time was really great loved it.
"land of the lost" fights back if you want to take up one of their buddies. I love this series!!!!!
i don't know how i stayed for the whole show/not, another great start to my Sunday morning in fact it's the reason i get up excited each Sunday more so than football...txs for sharing(like and subscribed)
That was a real session thing flying across the room a bit of laughter enjoyed it Mussti 😂👍🤠
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!
