Mark,
Now you have gotten me concerned! I changed
the muffler and that didn’t seem to have any effect on the EGTs, so I don’t
think that is the cause, but I don’t want to damage any orings. What were
the temps you were seeing when the orings were damaged?

Brian,
I had high EGT's at one time. Turns out it was due to an overly
restrictive muffler. The high EGT's damaged the o-rings resulting in an
engine overhaul. Could this possibly be at the root of your high EGT
readings?

My engine is now running just the way it
should, temps were 180 or lower on a 75 degree day, but my EGTs have always
been high, really high- above 1800 almost all the time. I think it may be a
calibration issue. My egt sensors are about 3 inches downstream of the exhaust
ports, and I am using Tracy's
EM2, calibrated at the stock settings. When the engine is stone cold, the egt's
read about 230 degrees, which I assume is normal because the sensors are meant
to operate at a much higher temperature. Any thoughts?
