My 40 hp Bigfoot 4 stroke has an intermittent miss at WOT. Is there a way to test the ignition system components. Some times it cuts out every few seconds, other times it is a few times per minute and some times the problem is non-existent. I was wondering if there is a way to test with out specialized tools, I can get access to some basic meters and such used in the auto repair industry, just need to know what might work and how/where to hook it up.
