Appreciate the reply, even the blurb from Pope Toecutter the 1st, but
if you have a look at the real data being measured today (the 21st
century) you'll see that the Old Wive's Tales aren't holding any
water. Regardless, you make your own decisions.

The CHTs are too hot. Check your fuel flow, check the baffles. Even
new, you don't want those CHTs that high! That's the recipe for
cylinder problems.


Jon,

The engine shop that did the overhaul told me, for the first 10 hours, to
run it full rich, and everything short of either red line or 400 degrees
CHT. With the mod, about 2700 RPM is just below 400 degrees CHT, and the
red line is now 2800 RPM.

I bought the EGT/CHT guage at Ken Blackman's recommendation. He's the
holder of the 125 HP STCs. He recommended the guage, because, he said, in
climb, at 9.3:1 compression, it can get quite hot, very quickly, and not to
exceed 450 degrees.

Normally, the Tomahawk has no CHT/EGT guage. So, I never knew how hot the
cylinders ran before the modification.
