my blaster stopped working, so i took it apart. Reeds are fine, compression is fine, fuel is fine, but it will noty start. the obly way is is to hold the throttle open and then it will start. My buddy thinks it is the electrical sytem. Ont the throttle box on the handle bar, is it supposed to be touching a little orange button when i m offf the throttle? and is there supposed to be a small piece of foam in ther too? Thanks a lot
