Carburetor

3 1/2 years sitting w/ same gas would do it forsure...I agree with everyone else. Clear the tank and lines, pull that carb and check everything then re-fill and I bet she fires right up! It takes more than a little bad gas to keep 'em down! At least you know it's turning over and not siezed up.

Stupid question, but did you change the plugs? Ballast resistor? (If they had one in 64 :scratch:) Check your grounds? Just food for thought. You know it's getting fuel from the gas issues, know it should be just a spark issue.

Let us know how it turns out! :thumbup:
