Unfortunately the problem came with the airplane, along with a lot of others.

Thanks for the CPS link. Good stuff. That's why I keep all my old catalogs. I have a Grand Rapids EIS that shows EGTs of about 1160 F at full throttle on the climb out. A bit on the cool side but then I'm running slightly rich to protect the engine. The plugs are a chocolate brown which agrees with running rich. Now that I can get back to the hanger I intend to check the enrichener circuits. It's about the only thing I haven't tried.
