need some advice guys. my bike is running abit rubbish. i went out on it today it started fine then when accelerating pop bang pop bang! it sounded like a machine gun. i played about with the mixture screw. finally got it to run spot on for 30mins or so. i stopped it for 10 then tried to start it again. it didnt want to know.

im starting to think the carb is the problem. im thinking about getting a better carb which one do i get
cheers adam

have you checked for spark ? take your spark plug out and put it in the coil then put the end on the plug on the cylinder head and see if you've got spark and if you don't check the output of your magneto with a multi meter
