95 50hp no spark

[cyrusperry]

i am at the end of my very short rope. i have replaced two coils and still no spark can anyone tell me where to find the triger switch and how to check it. i have also traced all the grounds and cleaned them. (HELP) by the way this thing was running for about 2 weeks and after about 20 spark plugs stopped working at all even with new spark plugs could this be a tell tale sign of my problem.

The first thing to do is get yourself a Clymer Force repair manual, or a factory service manual.

There are very detailed troubleshooting and testing procedures in the manual.

The stator (generator) is up under the flywheel.
The trigger assembly is there also.
The switchbox is on the side of the motor.

All can be tested, and through the process of elimination, the problem can usually be pinpointed.

If so its the voltage regulator and its not cheap.
You could probably find it cheaper someplace else.
