View Full Version : more carb questions

My problem is the boat starts to sputter then goes away then comes back and so on and so on. It runs fine at idle but does this at any rpm. Plugs are good fuel filter is new. Two weeks ago everything was running good. burnt off 2/3 a tank of last years fuel again with no problems. Topped off with 10 gals. of new fuel and the sputtering started lightly, the next day filled the rest of the tank (from the same station) and it got worse. Could it be the gas or do I need to rebuild the carb or could the carb just be cleaned?

When you describe sputtering, do ya mean the engine is dropping a cylinder? If so that would lead me to believe you are having an ignition problem like a plug wire... those tend to come and go based on engine load.

I'll start with plug wires. Thanks. Does anyone have the part # for them? It's a 93 with the 351 HO.
