My neighbor has recently picked up an 02 WR426 that did not run. We cleaned the carb and it ran good for a few seconds then just died. We took it back off couldnt find anything wrong, put it back on and now its like the float is getting stuck open. we hooked it up with the bowl off and manually moved the float, and the gas shuts off. I am kind of lost as to what it could be. Whatever it is, it is causing a lot of gas to flood the cylinder. Any help would be greatly aprreciated!!
