my problem started with no spark, then i read up a bit and unplugged the rev box and all was well. with the box still unhooked it runs for about 5 min or less and slowly dies out like a fuel problem, but it has no spark. could this be due to having no rev box on it? or another problem like the stator? their a bit pricey for testing purposes. any help or testing specs or procedures will help alot! thanks alexfeitel@comcast.net

What are you calling a rev box?

Are you losing spark on all three plugs?

Very involved, but easy to follow troubleshooting guide in a Clymer Force repair manual.
