ok so i just got my blaster going again a few days ago after i completly tore it down and built it from the ground up. it is running amazing and has plenty of power but it wont idle. it only stays running if i feather the throttle. also when im downshifting from any gear when i clutch it i have to keep feathering it or it will die. i have adjusted the idle skrew and it has no affect. any ideas?
