What a great group of people ! Thanks to
Lynn, Ed, Dspiegel, Craig and Wayne. Took all your responses and started
working thru them this morning. I never would have thought that the gap
around the carb air intake would contribute to the problem. Sealed it and
took the plane up and got a 13 degree drop in oil temp ! Put a permanent
fix on and waiting for some sealant to dry, then I am going to restrict ( a
little ) the air flow coming in at the base of the engine and see if that will
increase the pressure differential between top and bottom of the engine and test
that tomorrow. Thanks again guys, I'm confident now that I can get temp
down to normal ranges. John Leonard
