Help me find my engine model

I've come close to answering my own question. on the tiller's parts page is says the engine is a tecumseh H60 type 7505N or 7506N. fyi i do not have the electric start if that makes a difference.

So if any one knows how to determine for sure which engine I have. let me know please.

This Tiller has been setting for about 15 years in a shed. It looks good and the engine turns easy. I'm pretty sure it was put awy with no gas in it, but a little oil in the cylinder. So hopefully it will start well with a clean spark plug and perhaps some carburator cleaning.

I've got to replace the gas and vaccum line first as the vaccum line was rotten. Might as well replace both.

I'll also replace the engine oil, and check the air filter.

Should I replace the gear oil? I think it tilled about 1/2 acre a year for 5-7 years.

Anything else you think I should do before starting it?

There will either be a sticker on the fan shroud under the carb, or the number will be punched in the top of the shroud near the spark plug.

I would replace the gear oil, don't know how much condensation can build up. For a spark plug, you could use a champion RJ19LM, a carb kit should be 631021B, and intake gasket 31960A. Those are universal kits, check your air filter, make sure its good, just a little oil in the cylinder, or even use some two stroke fuel.

Hope this helps

jtclays was nice enough to take some pictures of his Tecumseh model number:







As for part numbers:

On the left side put Tecumseh for brand and whatever number you find stamped on top of your engine for the model.

And you are correct. H50/HH50 is 5 HP, H60/HH60 is 6 HP, H70/HH70 is 7 HP. H is a light duty engine made mostly of aluminum and HH is a heavy duty cast iron engine.

Thanks Adam. It was right where you said stamped in the shroud next to the spark plug. H60 75505R. Overlooked that when I was looking all over for it yesterday. The manual said it would be a 75505N or 75506N. So good to get the right one, though most parts appear to be the same. The breather tube is a different part number.
