Wow, finally, Captken you probably opened a can of worms on this one. I've tried for years to figure this out and the only two guesses after I've been able to come up with on a multitude of Kawas is what is the difference between this and a Kohler ?, (tappets instead of hydraulic lifters), and ambient temperature. The engine can start and run beautiful until the temp drops, (like today) and sometimes the only way to pop 'em off is with ether & sometimes not even then. Read a bunch of interesting possible solutions on here, but I don't believe you bought a bad engine, every damn Cow-a-socky I been around has developed this problem sooner or later. Keep us posted because I'd love to know the fix as would a lot of lawnsite mechanics, Good Luck
