i bought a 88 20 hp used it twice ran great my friend took it out on the third time after a short use it died let it sit all night then it started next day. took it out a week later started up ran less than a mile then died sat 3 days and cant get it restarted. fuel is good but no spark(used tester) found frayed wires and fixed them still cant get it started. Found the switch box to have some damage but not sure if its working how do i test the switch box, stator, and anything else that could fail. i dont think that both coils went at the same time. please help have big trip coming up wont make it if i cant fix it thanks jason
