    1994 Johnson 175, tan/brown film on spark plug

    Hey all, just got this 1994 Johnson 175 on a boat I purchased. I ran some seafoam through it to help clean it out some and pull the plugs and noticed one plug had this tan color to it, and figured it might be just part of the decarbing. So I put new plugs in like I've read you're supposed to...

    Hey all, so I finally decided to start working on this 2002 Johnson 9.9 4 stroke I've had sitting around for about four years now.

    1977 Johnson 200 Spark plug carbon buildup

    Hey all, so got my new to me Johnson running smoothly in a bucket. However, I noticed a few of my sparkplugs aren't looking so good. My top starboard spark plug seems to build up with carbon pretty quickly, while all the others don't seem to have this problem. I don't run it more than 3 min and...

Well...
