Tomahawks are infamous for relatively high CHT's. The modification to 125
hp makes it even worse. I'd say that 400 degree CHT's on a brand new engine
at full power during break-in ain't half bad for a 125 hp Tomahawk.

Paul could post his question to the Tomahawk group in Yahoo, and I think
he'd find that these temperatures are typical or maybe better than typical
for this installation.

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.

I just had the O-235-L2C in my Tomahawk overhauled, and the 125 HP mod
performed at the same time. Now it is getting 2700 RPM at just under 400
degrees CHT, during break in, and cruising between 100-105 knots. Before
the rebuild, cruise was about 2400 RPM and about 90 knots.

I'm very happy with the engine mod, and would recommend it to anyone
getting
an O-235-L2C overhauled.
