Typical popoff pressure on alky? Rubber or metal tip inlet needle? Fulcrum arm height? Reeds malfunctioning?Got a new one ive run once thats flooding crankcase and causing ALOT of raw fuel out the exhaust pipe on a 125 2stroke.....motor ran great, took off great and no high end stumbling...any other possibilities?
 
I had the same problem this weekend except mine was hard to get cleaned out, Turned out to be the welch plug had came loose fixed that and worked great
 
I have pop off set between 6-8 pounds on alky. If you’re in that ballpark already go through the carb and check your fulcrum height, and your needles and seats to make sure there’s no issues. If you’re able to keep it cleaned out and running without fouling plugs I’d leave it. If it’s fast being that rich you’re keeping the motor fat and cool which is exactly what they need.
