Whats up, I just switched from a twist throttle to thumb throttle on my 98 blaster, and now the carb is leaking gas from the bottom over flow tube. I took it off cleaned it, cleaned all the jetts, float seems okay, i put it back together and still its leaking??? It never did before i put the thumb throttle on. I just couldn't keep that twist anymore, i was gonna hurt myself...lol any suggestions? Does that float need adjusted to accomidate for the thumb throttle??
