Bob,
I have got a two blade MT electrical constant speed propeller.
So I preset the rpm I want the prop to turn and the control unit keeps
for example the engine at 5200rpm even with the throttle at 40%.
So the power the engine delivers cant be calculated via manifold pressure and
rpm. As there is no indicator for the pitch of the blades.
So I can not rate the lack of power by numbers.
The "longer suction tube" are the 15mm the carbs have been retracted from there
original position due to the carbheaters. The length the carbheater body is
adding.
Sorry for my bad phrasing.
Juergen
