I noticed that I had a leak coming from the pump lever on the front of the carb, I put a new nylon valve,and pump diaphragm.Once I got everything put back together,also put on a new fuel filter.I noticed that the carb was just spitting gas out of one side of the carb,then it stopped completly,it worked fine before I changed those part.Any ideas on which way the pump diaphragm goes on?
