It doesn,t take much of a rich mixture to carbon up the plugs with todays gasoline. If you are driving it regular & they are getting black you are running too rich. If it,s all slow & idleing, moveing around the shop you have to clean them occasionally. The extended tip plugs work the best. Like AC R46s. I bought some Champion plugs a while back & they broke real easilly & there was nothing in side the insulator, Just space. I keep a spark plug sand blaster in the shop & clean the plugs on the trucks we are working on when nessesary. They are available from the discount tool shops for $20-25.


They say money can't buy happiness. It can buy old Chevy trucks though. Same thing.
