I have a 2003 Moomba Outback with a Indmar 310 carb. Last summer it wouldn't run very good, it didn't have any top end and would stall when idling. I had the carb rebuild and it has top end now and will idle fine when cool but after it heats up it will start to spudder then shut off (if idling for a few min) sometimes it will crank back but most of the time i have to hit it with starting fluid.
