Hello John::
I would suspect #3!! Airflow! Baffling
needs to be pretty rigid to force the air from the top of the engine (High
Pressure) around the cylinders to the low pressure side of the engine. The
biggest culprit is the Heavy gasket that goes transversely across the top of the
engine that separates the front of the cylinders from the accessory
section. This gasket must lean forward toward the propeller so that it
acts like a ram air scoop when the top of the cowl is installed and forces the
air down through the fins on the sides of the cylinders. If this flap
points to the rear the ram air will escape around it and will not properly cool
the engine.
Hope this helps,
Wayne Woollard

Replaced all rubber baffling in the engine compartment.(needed it, old baffling was rigid and not flexible)4. Richened up the mixture.Anyone have any suggestions as to what else might be causing the problem?[EMAIL PROTECTED] N3644H============================================================================== To leave this forum go to: http://ercoupers.com/lists.htm Search the archives on http://escribe.com/aviation/coupers-tech/
