What else to check?!? No matter how/what I try, the thing is a BASTARD tostart when hot. I've got a marine battery in the thing now, because thelast battery couldn't take the billion or so times the starter had to turnover for the thing to catch.Compression is above 100 and even on all four cylinders. Spark plug gap isbetween 25 and 28 thous'.Head temperature sensor checks out okay, about 2.2k at ambient (70 degreesF), down to 50ohms when fully hot.The starter turns over no prob, especially with the deep cycle battery, butit takes persistance and dumb luck to get it to spark. New condensor,points, cap, and rotor. The bus idles great when cold (cold start valveworks for a few seconds, then to a slightly fast idle, then down to a prettydecent put-put-put staying more or less at 850) Advance is set rightexactly where it should be.The bus runs GREAT until I shut it off for the first time, and then for thenext hour or so, it's a total bitch to start, and when it does finallycatch, it idles like -CRAP-. Real slow and lumpy. Once it runs again for alittle while at highway speed, it idles fine until you turn it off.???????????HELP!!Thanks!-Matt
