New Best on Friday Night!

Look rich to me and either you have too much timing or you need a colder spark plug.

But you really need to shut it off at the finish line, cost out of the way and pull a plug again.

If that was pulled out fresh of a run i would say that it is WAY Rich. but as has been said already, if you have the wrong power valve for your set up and its opening at idle. Well It would be way rich all the way back to you trailer.

I'm no expert on reading spark plugs. have been doing it for years, and now trying the O2 gauge way.
