of use the turbo charge is stuck. Pull off hose and clean with
something like CRC 5-56 to free it up. To stop it from happening
again from time to time bring the engine speed up to over 2800 and
let it run for 10 min or more that will keep it free from carboning
up and keep the upper end of the engine free of carbon as well.
WILL NOT HURT THE MOTOR BY DOING THIS>>>> IT IS MENT TO BE!!!

There are a host of reasons why the engine may not make RPM:

2. RESTRICTION IN THE AIR SUPPLY:
a. Turbo blades not turning easily due to:

b. Clogged or collapsed air filter.
3. EXCESSIVE LOADING OF THE ENGINE:
a. Dirty Prop (you already verified this isn't the problem).
b. Transmission malfunctioning (I haven't a clue how to trouble
c. Dragging shaft brake. (rule out by direct observation).
d. Incorrect prop or prop malfunction. Can you make better RPM
Be methodical in trouble shooting. Verify each component and

Never miss a thing. Make Yahoo your homepage.
has been on a light load for a while that it should be run up to
revs to burn off the carbon build up on the turbo fan. This should
done several times until white smoke is cleared from the exhaust.
Having done that it is important to let the engine tick over for a
