Blenheim IV

[nakedsquirrel]

Has anyone been able to fly the Blenheim without blowing the engine on full real settings? I have been having trouble and I feel I have been very conservative with the engines

Engine RPM 1600-1800
Engine Boost 2-3 (12 o'clock position)
Oil Temp between 40-55 degrees
Temp Gauges (to the right) between 2-3
I've tried with Carb heat off and on
Also with Boost cut out off and on

Nothing seems to matter. The engines run for about 10 minutes and die.


Temps are fine, boost is fine, and RPM are fine, so What am I missing? Is there a special switch I need to turn on?
