Are you sure that both cylinders are firing. I had similar sounding symptoms and found one of my ignition modules was bad. It would fire but not all the time. It is a bit of a bear to change as you have to remove the battery and platform screws enough to flip it up. You also have to remove the top of the firewall and loosen the bottom. Then remove all the screws from the fan shroud (the bottom two are a real challenge). Then you can move the shroud just far enough to access the flywheel and the modules. Or---------
Remove the front grill, remove the engine bolts, Remove the bracket with the throttle and choke cables and the wires going to the carb, take the bolts out of the rag joint, and remove the wires to the starter and jerk out the engine. Also I found the slave wire between the modules was bad and it shut down much better with it repaired.
