Hello Group, I am having an issue with my 1985 40 Johnson. It will start great, idle for a few minutes, then start acting like it is running out of fuel, starting with the top cylinder. It will caugh, then quit and run on the lower cylinder, then the lower cylinder runs out of fuel. I have replaced the diaphragms in the VRO pump, of which I have plugged the oil line and run mixed fuel. I have replaced fuel lines, pulse line, and have checked for crankcase pulse, and pulled the fuel lines, and fuel comes out when motor is cranked. I replaced needle and seats in both carbs, and set float, but not float drop. New fuel line and connectors. .Visually checked for any leakage at all connections, all ok. Primer bulb pumps and gets hard as it should. Any ideas on what I could check next?
