Hey, I have a problem with my moped that if I give it full throttle at low rev it makes the bwraaa dying sound but if I get it up in mid/high - high rev then it drives like a dream flat out (40-50 mph) acceleration is also down in the start. no four stoking at top speed. I had a 64 jet in and then the problem were I could only drive with 1/3 throttle but would die at full.
