Tecumseh H50 Snowblower Governor Question

[threeputtpar]

I tinkered with it a little more last night (my wife thinks I'm becoming obsessed with this thing) and cleaned out everything really well.

Fired it up and plunged it into the snowbank and it still bogs down somewhat. For diagnostic purposes, I turned the choke on one click and it really seemed to stop the bogging. Only problem with that is that it doesn't run at full power with a partial choke and less than full fuel.

I guess I'll try to warranty the carb and go with the adjustable one.

I had a newer Tecumseh snow king 5 hp ohv motor that I had to add more and more choke. It turned out to be the shear key on the flywheel tearing. It was almost completely cut.

Replaced it and never got the engine to run again.

I had a chance last night to go out and check my carb/governor settings, thanks to a really good video on youtube. I watched it a few times, wrote down some notes, then went outside to check mine.

First observations:

I bought the snowblower last year for $50 with a bad engine. The crankshaft was galled and was leaking oil badly out of the output side of the engine. You could take the crankshaft and move it up and down, there was so much play. I have been slowly rebuilding it over a year replacing the side cover, crankshaft, etc etc and just got it finished last week. It started right up and runs great. Needs a carb rebuild, genuine Tecumseh rebuild kit on the way.

The previous owner told me it "loses power under load". Apparently, instead of rebuilding the 30 year old carburetor, which leaks fuel out of the adjustment screw at the bottom of the bowl, he turned the governor high speed adjustment screw ALL THE WAY IN! The engine must've been running 7000RPMs or more at WOT. No "wonder" the crankshaft was ruined; Tecumsehs are known for throwing rods if the RPM's are too high!

Also, the governor spring was in the wrong hole AND somebody had adjusted the governor arm and obviously didnt know what they were doing because it pretty much disabled the governor, thus why it would bog under load. I backed the governor high speed screw out almost all the way, by ear, it now runs at normal speed WOT, adjusted the governor, now it no longer bogs when it hits a snow bank, and ordered a carb rebuild kit.

Thanks to this thread, and that video on youtube, I spared another Tecumseh engine and my spare time chasing parts. Cannot believe what some people band-aid to fix a simple problem, ESPECIALLY given how crazy easy it is to rebuild a Tecumseh carburetor!

Oh, and since this is BITOG, I refilled it with Mobil 1 Advanced Fuel Economy 0w-20.

There is a sticker on the side of the crankcase calling for 5w-20. Im very happy with the work I have done and cannot wait to get the carb rebuilt. This is on an older, mint condition Bolens 524.

I chuckle when I hear stories of how some people Jerry rig stuff to get it to "kinda" work and end up ruining a perfectly good piece of equipment. Glad to hear that you're setting things right with this snow chucker, and you got it all figured out in the end.

I actually called the place I bought the emissions carb from and the mechanic/owner said that he's had a few problems with the non-adjustable ones on older machines. He let me pay the price difference and sent out an adjustable one for me to use. I also get to keep the emissions one, so that bad boy will be torn apart for the sake of learning.

Thumbs up! (sorry BITOG does not actually have a thumbs up icon, I have to type it out...lol)

Im glad to have found this snowblower- they are very solid machines and this one, other than the engine work I did ($30 in parts) and the governor adjustment (Free), its in very good shape.

Ah ah!!! So cool, thanks for showing me that. I guess I looked over it earlier.

Wow I have exactly one like that, just labelled Stiga 610.

And here she is: Stiga 610 aka Bolens 524

Haha Lars! I think a few years ago you posted that picture too when we were talking about them here. Looks 99.9% identical to my Bolens. Great machines. The hoarder in me (joking, Im not a packrat by any means!) finds myself searching on craigslist and ebay all the time. I always think if I can snag them up for cheap, tune em up, I could resell them at a profit because these snowblowers are so rugged, they are far superior to anything sold today, IMHO.

Currently I have two - the Bolens 625 my Dad gave me when I moved out 10-15 years ago, and now the 524. I enjoy working on them.. keeps me outta trouble, lol
