Does anyone know of a place in-state, preferrable the Grand Rapids area (holland is even better), that does ultrasonic fuel injector cleaning? I have a feeling my 90hp 4 stroke outboard is seeing some of the effects of ethanol in the gas as my fuel line rotted out last year. Since I'm replacing it, I'm thinking about getting the fuel injectors cleaned while I'm at it. I had a few trips at the end of last year where the engine wasnt idling well and it seemed like a fuel issue. Priming the bulb seemed to get it going better at times. I found a few places out of state that will do it, reasonable too. I'd rather not have to ship them if I can get it done locally.
