Hi everybody ,I'm new to the forum and I have a 99 blaster with factory everything. last year my blaster made a thud noise and them it would'nt go anywhere. it would idle like crap but when letting out on the clutch it wanted to die. i got to looking and a reed valves had broke so i replaced them and were off and running again. yestedday it made the same noise and had the same crapy idle and now i cant even get it to start . i check the reed valves there fine , i put in a new plug, took the head off and the piston looks good, i shifted the transmission through all the gears and it works fine. i checked the float in the carb (working fine). but there is a sensor or something on top of the carb were the throttle cable runs to and im not sure what it is or were the adjustment screw should be set at. maybe thats my problem??? can anybody help?? Thanks
