Well I have to ask. If you are sure, then you need to adjust that valve into spec.

To repair the engine correctly, it would require a complete correct "valve" job, which most of the gang here have never witnessed.

But if you adjust your valves back into specs, you will likely get her running again for a while!

Fish: Think I know how to find TDC on a four stroke engine. There is only on TDC on a four stoke however there are two occasions that the piston is at the top of its travel. Anyway it was 1/4 beyond TDC which I believe is the correct position to read the valve clearances and they are as I reported them. I did find a bunch of grass packed under the flywheel/blower housing. It is possible that it overheated.

Correct position for valve adjustment is 1/4" past TDC, not 1/4 turn, you may already know this as well as engine cold.
