Re: cold carbs, questions from new boater
Welcome to iboats, Mark.
Carbs will chill down with use. Combination of air flow and fuel vapors will cause it.
Tune up can be many different things, depending on the engine and its condition.
Could cost $30 to have it looked at and have the spark plugs changed.
Or could cost $400 to have the waterpump changed, fuel pump rebuilt, spark plugs, points/condensor, carbs rebuilt, new fuel filter, etc.
Sorry to be so vague, but there is no answer until we know what engine, and its condition.
