Have a 2002 grizzly 660 that had fuel leaking and a bad run away problem. Pulled the carb and disassembled. Float pin was seized and had a diaphragm tear. Never had throttle issues until rebuild was completed and reinstalled. Carburetor idles great. However, just touching the throttle stalls the engine. There is no sputtering, coughing, burping. It just dies with the slightest touch of the throttle. Tried adjusting it multiple times with no success. Finally pulled the carb to be sure assembly was correct. Everyone's good. So before I reinstall does anyone have suggestions or have experienced the same ?
