Any info on trouble shooting this ign system would be nice. Unfortunately, I don't have a manual and not sure what year it is. It's obvious I'm going to need a lot of help here. Probably a good place to start is to explain the problem.<br /><br />This motor quit suddenly, no sputter, it just quit and never restarted. Lots of fuel to the combustion chamber but no spark. An Ign circuit diagram could be helpful.<br /><br />Any suggestions would be greatly appreciated.<br /><br />Best regards to all.<br />George. Ont. CAN.
