is there a overflow on the fuel pump on a 02 440 mxzx, sled starts fine but idles bad and has a little fuel coming out the fuel pump not sure if its a over flow. carbs are clean new plugs and 135 compression both cylinders.

There is no reason that fuel should come out of the fuel pump, probably has a bad gasket. I say either rebuild the pump if you can or buy a new one. A leaking fuel pump would cause it run poorly. Best of luck!
