    I start my ped let it warm up abit then rid to college an at the lights i noticed my carb was dripping fuel. I took the bowl off an made sure flat wasnt stuck. Was fine. Could it be that i have over jetted? Or a dodgy auto choke?

    Help apriciated

    bit of crap in the hole for the needle jet maybe...stops the needle sealing the hole when the float gets to required height

    I wouldn't use instant gasket unless it's fuel resistant which most of it isn't , you risk contaminating the fuel.

    As above the only real thing that would cause this issue is a dodgy float height or worn needle . Possibly a free flowing fuel tap but the needle should still shut off the fuel flow to the carb bowl.

    Is the float height even adjustable on your carb?

    Did you touch or change anything to do with the carb recently and does it still run as it should?
