OK this has got to be one of the better mods on this motor. i lapped the valves and put a washer under each spring. motors back to one pull starts. compression is up 50 percent compared to it was new.
makes it hard to pull start but i can live with it.
ex valve was burnt and that's without a open baffle muffler. maybe high rpm?
anyway lapping and shimming works....
