Are you running the engine with gas that has been in the tank for 3 years? |

Carb could be internally varnished? |

Do these engines have an Idle air control valve - on my Sundancer it was nearly a once a year event. |

On an old carb engine it could be many things: vaccum leak -->bad carb to manifold gasket clogged idle circuit in the carb-->carb needs thorough cleaning float setting off, if too high it will cause the engine to flood I'd recommend finding a place that rebuilds marine carbs and let them try to re-do yours. If it works, great if not then consider buying a re-man carb, if you can find a reliable vendor. I've had my 1988 Rochester Quadrajet re-built 2x in the years I've had it (since 2002).... |
