Valve lash gap

Where can I find the valve lash gap for a Tecumseh Model LEV100? (3.75 Hp mower)

Why is this data so hard to find? I would think that there would be a web site with technical data for all Tecumseh and B&S engines. Is there such a place?

Thanks,

Hi slowillie!

I don't have the specs for that engine either, maybe someone else here does. I would set them at .010 inch, both valves. That is what the older engines that your engine is based on were set at. Judging by the model # and the fact that my books don't show it, I am assuming it is a newer engine. My Techumseh books aren't really up to date, lol.

It is not real new, I bought it in 1998.

It did not last long, however, before it started running poorly. I should have been working on it 2 years ago, but did not want too rush into it!!!!

The exhaust valve is quite a bit less than 0.010. I was thinking that that might be the problem.

Thanks again,

Valve lash specs.

The adjustment is .008 cold. The stem can be trimmed to specs. Try a compresion test cold then hot. Just to be sure it's valve related.
