So your saying that each time you hit starter it will spark once? Or you only got one spark the first time you tried it.It was running before. I have 10 or so volts at the coil. When i use a meter to read the plug voltage it is only 10 or so i think it should be more. It is a new coil and i did have it at around 30v at one time but i cant get it again and it also had a spark on the plug but only one time when u initially hit the gas.
