A little choke needed to start and run?
I need about 20% choke to start and run the engine. Even after completely warmed up. If the engine is hot (~180*) and I kill the choke the engine will stall. At nearly any throttle. So some choke is always necessary.
Thoughts? |

Your carb is clogged or otherwise running very lean.

Thanks. I thought that it could be an idle adjustment. Doesn't sound like it, eh?

Not if it happens at full throttle too.

As noted the idle adjustment will not affect high speed operation. Concur that the problem sounds like an air leak somewhere. TRUE GRIT |

I would pull the carb drain/main jet access plug and drain it into a clear container and see if you get some gunk come out with it. If you have a mechanical fuel pump, give it a few strokes to flush a few ounces of fuel into the container and see what you got..hopefully clean fuel with no hitchhikers.
You should need 100% choke to start a cold motor, but after a few minutes, zero choke for normal operation. What fuel are you running? Corn laced (ethanol) or E-zero? How much fuel do you burn thru in a season? I do not like ethanol fuels sitting in these old carbs for extended periods..I have found them to leave yellow honey/gel like gunk in the innards if they sit. If you use your boat regularly, not as much of an issue.

Kill the choke and engine stalls. Does sound carb related. 90 octane ethanol. Haven't done a season yet. Just drained the gas tank and put new fuel in from the automotive gas station. So I've checked the lines, put on a new fuel filter, and the fuel pump seems to be fine. |
