I know this isnt a buick .. but, it's keeping me from working on my BBB because if I don't fix my 20hp merc carb I can't go Duck hunting. If I can't go duck hunting I'll explode. If I explode no BBB.. Here is the question My 20hp Merc lost the choke squirter and wouldn't start. I put a new diaphragm in along with all new gaskets and now it starts right away and runs good. After it runs for a minute at idle or seconds going up river it will run out of gas and quit. It will only run if you pump the primer bulb. I thought it was the float, checked it and it looks ok. Thought I might have put the fuel pump in wrong, checked that sevel times including putting the old gasket / Diaphragm back in.. No luck, keeps stalling after a minute or two. Any suggestions?
