stumped!

Try blocking off the fuel hose and spraying starter fluid down the carb throat (hold throttle open while spraying, then close). If your spark is close (say TDC to 30 deg ATDC), it should run on the starter fluid. You can keep giving it shots to keep it running. That would tell you if it is a fuel problem.

^^^^ This, or u can try just turn the distributor a little advanced I know when I first fired mine it would not start with it set at tdc.
