Chuddy,
You say it didn't run right last year......What was it doing or not doing? When did you replace all of the things you listed? This year or last when it wasn't running right? Am assuming your getting gas....?! (I know it sounds redundant) but, have you double checked the firing order on your plug wires? do you have a fuel filter on it? How old is the gas in the tank? Take it one system at a time.
you'll find it. Did you adjust the valves with the engine cold or at operating temp?
