Re: Winning the Lottery !!!!!

if you are losing spark, it could be switch box or distributor trigger. Learn how to check the switchbox from CDI website (I believe you ground a terminal on the switchbox) and do the check when it fails on the lake. If the switchbox checks good and you have no spark......look to the distributor sensor.

Re: Winning the Lottery !!!!!

Changing parts is the most used, most expensive and least effective method of troubleshooting known to man, BugF.

Worst of all it often introduces faults that were not there before.

Forget that so many parts are new and troubleshoot logically. Start with Schematic's advice.

Good luck. :)

Vary rare to see erratic fire on a distributor style ignition system, and if it is erratic it usually the trigger or carbon tip in cap...
