Spark Plug Reading
My engine has been running a little rough lately and smell rich at idle. I decided to pull the plugs and see several that show rich mixture and a few that look pretty good. (see pic)
Before I pulled the plugs, I checked cylinder temps at each header tube close to the head and noticed temps varied from 160 F to 240 F.
Plugs are Autolite 3924
Any ideas on what may be causing this?
