5 liter 1999 Mercruiser with a carb. Idles rough, takes at least ten minutes to warm up to where I can rev the engine while in neutral. At higher speed / rpm the engine sounds great and will run as fast as it ever has. The carb was rebuilt by a mechanic at the beginning of the summer. Some of the gas from winter storage had
stayed in the fuel system too long and the carb had to be cleaned out after the rebuild but the tank was run almost to empty and at least 1/2 tank of fresh gas (with added stabilizer) has been run through. Would I be wise to try some kind of gas additive to help clean it out or is there a chance the carb is not adjusted correctly?
thank you
