my old 960 always has started great. yesterday i was using it and it started sputtering, backfiring. i had just filled the tank so i drained the carb into a glass, didnt see any water. finally it started and i drove it to the garage and when i got it in there it started acting up again. this morning i started it and it didnt run very long and did it again. check the fuel again. dont see any water. pulled no 3 plug and didnt get any spark. checked voltage, 12 volts at coil, 12 volt at distributor, 12volts on long part of points. no voltage on short piece of points.no spark across points when i turn it over. is that a sign the condensor is bad. only think i could think off. neee some input. thanks
