Can it be as simple as adding a can of seafoam to the fuel? I've never used it. Will this possibly cause a fouled plug?
I almost always run ethanol-free, but I have put fuel with 10% ethanol in when I couldn't find non (no more than 10 gallons at a time). My motor probably has 50 hours on it. I assume mixing the two fuels + time has lead to the rough idling.
