[QUOTE="pafree, post: 334003, member: 12776"] my new to me 20 hp johnson had the same issues. i put a carb kit in it because it was missing the rubber gasket/weird shape o-ring around the idle adjust screw but still didn't help. the engine would run for a couple of minutes and then stop. i would pull the fuel line off the carb from the pump and get the same results you were getting. i rebuilt the pump and it solved the issues. does it have a real choke or a primer choke?
