OK Tell Justin to take the fuel hose off of the carb and hold the line in some kind of container and you turn/start the engine and see if you have gas pumping out of the hose into the container . If so I think the problem might , I said might be trash or a bad needle and seat in the carb. The pump should pump a good bit of gas pretty quit ,so be prepare to turn off engine when Justin starts hollering. He should be able to do this. I have seen a lot of needle and seats even in new carbs and even overhaul kits right out of the box be bad here lately. Good Parts are getting really hard to find. Keep me posted.
