gene,
Sometimes brevity is good, NOT when trying to find a problem. Do I understand it doesn't idle ? CARB idle circuit, manifold gasket leaks, primer cup vacuum leaks, maybe a bad plug that only fires at higher RPM (hiher voltage).

learned this trick on f-20 idling smooth from my dad who would of been 86 this year. set the plugs at .030 not to ihc owners manual spec's . original spec's were for distilate or kerosene fuel not todays higher octane gas. even in the early 50's regular gas was only like 70 octane. this would be a no cost experiment, but might solve your problem. good luck leroy
