I do alot of racing but I am just wondring if it is time to get a new motor
It might be time for a new carb, the S7 has the older style carb with idle screw on the bottom of the carb, the newer.style has idle screw on the top side, the shark, b10, WS9, and some of.the newer Nova Rossi engine, try to pick up one of those, that will probably solve the problem,while your at it,put a new conrod in it, probably go another 5 gallons.
