Ok my turn to eat humble pie and how easy it is to overlook the simple stuff.. LOL.
My running hot issue ahem,, ahhh , turned out to be the carb was loose causing the engine to run way lean. i didn't notice it until i was checking the vacuum for the primary rod power valve. Vacuum seemed way to low for the cam im running. tightened everything down.. 180 degrees ! yippeee! Now i have a good stable vacuum 13 to 14 inches, so im going to change out spring this weekend.
