I can't find out what is wrong with my sled but it's getting way to much fuel and bogging out when you shut the fuel off it runs fine till you have no more fuel thinking some one put the wrong fuel pump.

Dirty carbs, sticking/dirty needle and seat's, misadjusted float height or saturated float's.

You may be on to something, A bad fuel pump diaphram can leak fuel directly into the crankcase thru the pulse line.
