Motor has new fuel line, rebuilt fuel pump, cleaned filter screen, cleaned carb(can't find a kit for this carb) and I added a in-line fuel filter between the bulb and the motor. Bulb don't seem to pump up. Motor only runs with it choked, dies when un-choking, When running dies like it ran out of gas after a few seconds. Before I added the in-line filter in run good except for a intermittent cough when at idle. In-line filter in fuel line a bad idea? Bulb never seemed like it pumped up right, always mushy. Any idea on finding a carb rebuild kit?
