I started having an issue with my engine at the end of last season. Now that the boat is back in the water, the problem persists. The primer bulb stays nice and firm, even after the boat has sat for a week or two. If I try and start the engine with the controls in the start position, choke on, it will just crank with no fire. If I manually hold the choke closed and butterflies open with the throttle in the start position while someone else cranks, it will start and run within 2-3 revolutions. Once it has fired up, I can shut it off and it will start every time with a single turn of the key. Within the last 2-3 seasons I have gone though the whole engine and either rebuilt or replaced the fuel pump, all 3 carbs, reed set, intake gaskets, cleaned low speed re-circulation circuit, etc.
Any thoughts/suggestions?
