Depending on how old it is, the carb could need new seals.

5italkart,

If you're having trouble with an inconsistent idle and not much bottom end response you may have a motor that has lost its pinch. You may want to replace the piston, sleeve and con rod or just purchase another motor. Once you have a motor with idle problems and you know the carb and o-rings and seals are all good then more than likely it's time to rebuild. Once the pinch goes away this tends to happen.

Regards,

Speyederjedi
