Hey y'all. I'm very new to outboard motors, but I have tinkered with 2-stroke mototrs in the past. I got a 25HP Johnson (Model J25RCEM) with a boat I picked up a few months back. I ran the motor for the first time yesterday and it ran pretty rough. It won't stay idling at all. I have to keep tickling the throttle to keep it running. Also, it doesn't seem to get to max RPM. After I got back to the house, I took out the spark plugs and there seemed to be a lot of oil on the plugs. It sounds like a carb cleaning/fuel filter issue. Any ideas? Thanks in advance!
