ahhh!! hello all, i have a question. I have adjusted my low speed and high speed screws nicely, but when i start to open up the throttle to get top speed, the engine stalls!!! (around 30-40 mph) Some say its the high speed needle that needs adjusting, I'm gonna get a new low plug too becasue e one i was using was almost dead. But i dontthink the plug caused the stalls. Can anyone help me???
