If you are = running=20 the aux pump on shut down, that would cause it. It is real easy = to test=20 the diaphragm......if you did it right, you leave the mixture in = idle=20 cut off and turn on the pump......if it leaks out of the impact = tubes it=20 is a bad diaphragm. The other thing it that the fuel spider on = top of=20 the engine is springloaded, so that when pressure stops it shuts = off the=20 fuel completely. If that is messed up , it will continue to flow = fuel to=20 the cylinders........engine usually keeps running for a few = seconds=20 after mixture is pulled to cut off......
