Tom,

No it was not revving high. The bottom end is rich if anything- pinch test is a tad higher than I normally run it~ 4 seconds till it stalled out. I didn't think 260F was too bad for sunday in Mentor (HOT!!). I was running 240's saturday and the tank was almost dry after every heat.

You made some nice runs Tom, didn't meet you, but I heard your name called all weekend long.

On my home track I can eliminate the problem by running it around 200F cause the track is small and fuel mileage is not an issue. I've run engines 240- 260 with no issues and good longevity. This thing has got me a little stumped. Guess I'll have to richen it up on the high end as to prevent the vapor locking.

Thanks all!!
