I have the plugs set 1 5 3 6 2 4... made that mistake at the beginning. Thanks for all the tips guys. I'll keep at it and post what I discover.
A quick carb question before I take it apart and rebuild: With the engine running as close to idle as I can get it, what should I see gas wise down the carb neck (i.e. a constant drip from the venturi, a slow drip, a spray?). I am beginning to think my float level is off and the engine is getting too much gas (the 3rd and 4th cylinder seem to be flooding... gas on piston). The carb wasn't rebuilt too long agon, but did sit for awhile. Thanks again...
