Thanks Dennis. It’s a deep dive into tech for sure. I’ve been asked about this job twice this year so wanted to capture the opportunity as I had the chance. Hope it helps someone someday
I burned one of these one lungers down as a kid… it sat for a few years beforehand and the crank seals dried up. Leaner was faster, but that was right before it seized up. Good times… new piston and jug and we were back at it.
Finding the aforementioned piston and jug is becoming difficult. You tend to buy up whole engines just to get good parts off it these days. Father Time is catching up with these things for sure. At some point there will just be the odd vintage sled on your wall or in your yard and that’s about it. Wait till the good NON-OXY gas goes away. UGGGH!
@@Letsfixsomething26 True enough. I also remember rusty steel inside the gas tanks... which also could have caused a lean burn condition... and I'm pretty sure we had issues with the ignition advance on that old 292 as well. I may still have the recoil if your buddy is bumming for one... not sure if I scrapped it or not. I just remember that machine was one you could hear from miles away... not of the brrrrp stuff like to day, just POP POP POP... and watch the TV screen in the house loose vertical hold when my brother got close to the house with it. Yep, it actually affected the UHF signal and messed up the reception. Good times.
I’ve been trying to think how to respond to this one. I do work for friends of mine and never take money, just get me some shop supplies or beer or whatever. I worry about the thing melting down and me getting blamed for it. Then things go sour quick. Hell I can’t even make a video without someone busting my nuts over this or that. Let alone helping someone and the engine locks up after I touch it. If you were close I’d help out but think I better just sink into the weeds and work my own projects. Humans have kind of taken the joy out of some of this stuff.
Actually great point. I guess I never have. New seals and send it, however you are probably right all things being equal. I did have a T1B340 that I was working on and the crankshaft had a huge rust spot in the seal area. That would of leaked for sure. I scrapped that crank, but yep that one would of leaked. Thanks for the comment.
The Salsbury puller tool is not that expensive. Most anybody who took small engine instruction after the late 70s, has no clue how to diagnose, repair, or maintain a magneto ignition system. I find they are fairly reliable, in some cases more so than 45 year old CDI systems.
Brian, I am very lucky that being an aircraft mechanic and having spent my entire career in general aviation, have spent considerable time inside an actual magneto. While the functions are completely different for a 4 stroke aircraft engine, the concept is the same. In other words, I get it. I get lots of people reaching out for help and some locally here in Western WI. I’ll help whenever and however I can. Now… CDI…? Ugggh!
And I do have pullers for other clutches. I was so pissed.. but fortunately the clutch was toast. We did salvage a lot of good arms and rollers for his other clutch he built up. So that’s mint.
I thought about that too. I wonder if it would of produced the same results….??? I mean expanding the aluminum would of occurred regardless. If I was faced with that again, I would of used a heat gun on that aluminum sheave…. That aluminum wound expand a ton and it would of probably popped off with just water. Glad it was junk in the end… made me a little more relieved I didn’t destroy a good clutch
292 = 26 HP 340 = 28 HP 440 = 32 HP Who cares… as long as it starts and returns to trailer under its own power that’s all that matters any more. Stuffs getting old. Like 50+ years old. Father Time is coming for all of em. BAhahaha
