Can I fix this hole with some JB Weld? Or do I replace the Tecumseh 8hp?



Cranked it up this morning to deal with about 5" of snow, ran about 20 feet out of the garage and crack. This is the classic thrown rod on a Tecumseh engine.

Of course, my real question is what sort of motor can I put on here to replace this one. The snowblower is a Spirit 27" with the 8hp Tecumseh.



This is an older model but it sat idle for a long time so the rest of the machine has a lot of life left. I'd love to save it from the scrapyard. Is there a motor I can buy to replace this one? I've read about Northern Tool stocking some things but that information is a few years old. Looking at prices of similar or suitable snowblowers I figure I have a max of about $250 to spend on an engine for this one. I might go to $300 but north of that and I'm going to look for a complete snowblower.




I do not know a lot about these things but I can follow instructions and will provide any information you all need to hopefully get answers.

Since it is a single shaft engine it will be easy to replace it with HF 301cc Predator engine. Since you have a 27 inch I would go with the bigger engine. Although I have a Predator 212cc on a 26 inch Montgomery Wards Gilson and it works well. The 212cc is very torquey and it seems to work pretty well in blowers up to 26 inches even. There is no way you can fix that hole with JB weld. Sell the starter from 8 HP engine to recoup some of your money.

I once fixed a cracked block with JB Weld and that engine still runs strong after two seasons, but you have one doozy of a hole.

Hopefully the starter survived. The few times that I had to deal with a blown engine, the starter gets hits so hard that it refuses to work.

Other parts can be sold, such as the crank shaft, fuel tank, flywheel, etc..

dang! took out the block & crank cover. That would be an ambitious repair to say the least.

Another used HM80 can be had for < $100. Plug-n-play.

Why buy a used L- head engine when you can have a new OHV engine that is much more fuel efficient and more powerful and quiet too. The 8hp Tecumseh engines were know to have connecting rod problems as you are definitely aware of. The new engines are easy to start with just 1 to 2 pulls of the recoil so a starter is not even needed

you do not know the history of a used tecumseh engine. buy a predator and be done with it. there are a lot of people on this forum that will try to steer you away from them, but they have never used them so dont listen to the crap they will give you about the clones

My personal preference...possibly the OP's as well.
