Hi Jay

High EGT an low CHT one cylinder:

Fouled plug,
Burned valve,
Broken ring,
Bad mag wire

That's according to the trouble shooting guidwe for my EI engine
analyzer.


Not likely to be the valve or the ring since it performed differently on one mag than the other. I would
suggest swapping the plugs and noting whether the problem moved to the other mag or not. Testing the wires is
an easy quick test with an HV tester...when I recently had a similar problem it turned out to be a spark plug
wire.
