Late 90's era Honda BF30 on 18' pontoon boat.
Purchased past summer, new to me, but used to the world.
Rookie mistake of trying to start it without opening the fuel vent.
Sucked a whole lot of water through the fuel system from a fuel separator that was full of water.
Drained tank, flushed fuel lines, replaced water separator.
Engine would start on full choke and rev to 4000 rpm, but would not idle down. As soon as you tried to idle it would stall.
Replaced spark plugs, removed carbs and replaced the slow jet emulsion tubes as they were clogged, replaced all gaskets and o-rings. Cleaned the carb body with repeated trips through ultrasonic cleaner and blew out with brake kleen and compressed air.
All throttle body tiny orifices were verified clean and with good flow when sprayed with brake kleen.
Replaced the fuel filter and lines on all carbs. Pilot screw set to three turns out.
Reinstalled carbs on motor. Fresh gas in tank, vent open, pumped bulb until hard, set fast idle, turn over...no start.
Tried half choke, nothing...tried full choke , nothing. Verified fuel in carb bowls via drain. Tried electric choke..nothing. Just turns over. Safety lanyard is attached correctly and trans is in neutral.
Removed carbs, disassembled them to verify that the slow jet emulsion tubes were seated correctly.
noticed carbs 1 and 2 from the top of the stack were wet inside carb bowl from gasoline, but carb 3 on the bottom was dry.
I have the carbs back together and ready to be reinstalled, however it is raining now. such is luck.
Any input or ideas would be helpful.
Thanks
