Ciao,
Have you checked the prop governor screen on the nose case for blockage?
See attached. Remove (19 mm wrench or socket), inspect for blockage
and clean this oil passage screen. Be careful not to round the corners
of the nut because it is a relatively soft aluminum. It is best to use
a socket or box end 19 mm wrench to loosen.
When you run up the engine on the ground to 70% and pull the prop
control lever full aft, the % RPM should come down to about 53%. Adjust
the stop on the prop governor control arm to bring the engine down to
53%.
Regarding the idle RPM, that should be adjusted to 26% with the idle
adjustment on the right side of the carburetor. The adjustment is under
the knurled cover on the right side. Remove the knurled cover and you
will see a slotted screw adjustment. See the M14 maintenance manual,
section 073.10.03, Figure 201, #3. This is the knurled knob I referred
to. Follow Task Card 204 to adjust the idle speed.
Hope this helps,
Dennis

Ciao yakkisti!
We have this problem ... operating the propeller controls in the
cockpit the propeller speed is not properly responding.For transfer
flight we normally fly with the prop at 64% to save fuel, sometimes we
fly at 59%.Using the prop command now it is not possible to set
properly the speed.This happens in a random way, sometimes it is ok
sometimes it limit our control onto the aircraft.We checked oil
quantity and oil pressure an they are good.We did NOT checked if
there are boring in the oil, but the warning light it is OFF.we have
already checked the command line, from the cockpit lever to the pins
over the governor, all this seems ok.the engine itself is running in a
perfect way.No high temperature no particular problems.we have a small
leakage of oil on the top of the mast of the propeller (since last
december)but this is not a big deal.Another strange aspect we do not
know if it is correlated is about the minimum speed on the ground:with
maximum prop and minimum throttle the engine remains over 30%.we are
thinking that it might be a problem on the oil duct bringing oil from
the engine to the governor;i think that the problem is in the duct or
in the governor itself.we are wondering if it is safe to fly in this
condition
Thanks for your help!
