Are you running the factory head?

This is with factory head. Thinking about running avgas this year. Just running Standard BR NGK plugs. Foul once in a while. What is everyone running?

B9's or iridiums gapped at .020 is what was recommended to me.

Factory plugs work fine. I prefer the iridium in factory heat range just for the extra insurance. Best suggestion is to make sure the spark plug terminal is solid not threaded. That way you don't need to worry about the terminal coming loose and spark arcing out in the spark plug boot eventually causing high resistance and poor performance.

If your going through plugs its a tuning issue. A rich mixture even at idle will foul plugs. You can only get a bog so many time before your plugs need to be replaced.

Its not easy to avoid on a t-smoke.
