Tommy,
I had similar issues to begin with, and after talking with Ed Anderson, he
steered me toward looking for an air leak. I was certain that I didn't have
any air leak, but after searching around the engine, I found source of the
air.
It doesn't take very much air to make it run high RPM's. My leak was a bolt
hole in the lower portion of the original intake manifold that I used when
fabricating the new intake. The bolt hole went all the way into the intake
inlet, which was letting in the air.
Now it will idle down to well below 1000 RPMs.

Hi Paul, I am really envious of your idle speed. Mine is around 1600. Any
ideas on how to get it down? Temps are outstanding too!
Tommy<><
Idle speed is: engine speed 800 rpm, with a prop speed of
around 400 rpm's. (2.17:1 reduction ratio). After 4 taxi runs and aborted
takeoff runs, the oil temp got up to 185 degrees. Oil temp was lower, but
unfortunately I failed to write it down and forgot. I believe it was around
160 or 165 on the oil temp. Outside air temp was 75 degrees.
