The final filter was a nice idea, but sadly not a solution as air enters the valve through all three ports; air comes in through the In port of course, but as the actuators move air up and down, air l ...

Yes, I sent the governor to MT for a stronger spring.

Asking the smarties on here.
I fly a Nanchang with a stock M-14p motor and an MT 250 prop. When I push the nose down my RPMs increase without touching the prop lever.
Assuming the governor is set ...

Has anyone installed intake valve guide seals on a Housai or M-14p?
Wondering if this isn’t a solution to leaking intake valve guides.
What is the m-14p valve stem diameter and what are the ID a ...

Brain trust:

I know that on an M-14p with a Russian M9F magneto, timing on the prop is set at 14-16* BTDC. This translates to around 22-24* BTDC on the crank.

Assuming an M-14p motor with CD- ...

Thanks Richard! My suction jet is 130 on my standard M-14p. It’s not a PF.
Accel jet is 060. I don't use the stock CHT sensor. I have an Electronic International multi-cyl instrument. I’d l ...

Vic, thanks for blowing up my thread.

Hey friends. I have a low time M-14P on my Nanchang. I typically have low CHTs in the 140C range even with gills closed. Fly out of SoCal so not a cold climate. I know Richard Goode tends to point ...

This can happen when the oil can does not fill. Did the prop cycle in the ground run?

I also replaced primer o-ring and used EZ Lube. Goes up and down great. But I have fuel coming out of the top of the primer on my Nanchang.

Dennis, sorry for the delay. When I set it in flight to 70% and then pull throttle back the RPMs stay steady.

I thought I once saw a plate that was designed for holding the mag from turning when removed from the motor. Does anyone recall?
Thanks, Gil

Dennis, I’ll try it and report back.

Looking for prop governor setup advice.

M-14P. Had a v530 prop. in ground runup, the prop cycled fine per the book to 50%. In flight I could not get RPMs below around 2000rpm (70%).

Have ...

Did you figure out what was causing your engine roughness?

Unlike the firewall snot bottle which only is pressurized by the compressor, the belly snot valve will always be pressurized as long as you have system air pressure. If you shut the main air valve th ...

On my Nanchang the elevator rests in the full up position with the stick all the way back. In flight it is perfectly balanced. I checked the balance bar and it does not have any weight plates to re ...
