You tell us.

If I'm wrong I'd like to know.


Red Box = No Fly Zone
At and below about 60% power, there is no red box.
At about 65% power or so, 100ºF ROP to Peak.
At about 70%, 125ºF ROP to 25ºF LOP.
At about 75%, 180ºF ROP to 40ºF LOP.
At about 80%, 200ºF ROP to 60ºF LOP


Makes no difference, carb or fuel injection.

| Jim,
