I've got an animal (actually 2) that seem to want to cut out after qualifying during the actual race. I can go out every practice and qualify with no problems then as soon as the main starts it quits on me. Sounds as it running out of fuel then just maybe will jump back if not completely die. Fuel is running out of the carb as its flooding sometimes not every time. I've tried 2 different carbs and the same thing plays out of both. New needles and new floats and gskts, cleaned and flushed after each race night and sprayed with Wd40 or triflo also....I'm really lost here...any ideas?
