some of ya'll were helping me about a month ago with a stumble. Well, I got the carb rebuilt thinking maybe that was it, and it wasnt. So now I am gonna go with it is a ignition problem. It has a petronix electronic ignition with a flamethrower coil. Possible maybe water got in the coil or something???? Maybe new rotor and dizzy cap? Though I dont see those causing this big a problem. I already did new spark plugs and new fuel filters.....any ideas?????
