Motor is new to me. I haven't put it in the water yet, but I've:
Changed L/U oil
New water pump
New thermostats
New plugs
New plug wires

It's a little hard to start cold, but runs fine and restarts easily on muffs once warm. I ran it for a couple of minutes after installing new plugs. Shut it down. Pulled each plug to take a look. Each plug has oil/gas residue except for the port side, top cylinder. It seemed completely dry.

Is this a carb issue?
