Re: Fouled plugs on 1990 Johnson 200hp
The first thing to do with that Johnson is de-carb it, especially if its had weak ignition issues. Use Deep Creep available at Napa or any auto store. Just read the instructions after warming it up and spray the crap out of that stuff. It will also clean the plugs at the same time, so maybe throw both sets in while you wait the 15 minutes and clean them up too.
