Mark & Jan, thanks for your kind words & for the record " " ... but latterly
Goggle translate is my friend and before that OCR / translation software :-)
Over the last decade I've re-drawn all the wiring diagrams by hand having reverse
engineered all the originally supplied schematics and researched the key devices
to find out how they work.
Hence our free ranging discussions over the years on voltage regulation, fuel displays
and 'shower of sparks'!
The work continues and only recently have I gained an understanding of how the
stabilising transformer helps manage voltage regulation on high current load transitions
and why Baklan replacement radios appear to work better with the original
antenna than new ones.
On that topic ... the original antenna has a crude 1st order RC high pass filter
/ splitter at the base of the antenna for the radio feed, and an LR low pass
to the ADF sense feed, so the bulk of square wave ignition noise harmonic energy
is filtered before it gets to the radio RF stage.
As radio is more your area of expertise than mine Mark I'd welcome your thoughts
on finding a higher order in-line high pass filter suitable for a transceiver
to work with replacement antennas.
Rob R.

Phil, you shouldn't get 2350 RPM on a stationary run up. It will be so when your
plane is moving on take off, when the aerodynamic resistance on the blades
is lessened as the prop is moving forwards.
Try it out and see.

That would be very true if the propellor was fixed pitch or even a
two-position type.
However this is a constant speed prop. controlled by a fly weight governor
that "knows" nothing about blade angle - only RPM.
Pre-flight (static) check of a correctly adjusted prop./gov. system (CJ 6
with Huosai 6a) with the RPM control set to TO would show on reaching full
throttle slightly over 2350 RPM (+ 15 to 25) momentarily with an immediate
reduction to 2350 as the governor responds.
On take-off as the propellor load decreases the governor senses an overspeed
condition and causes the pilot valve to slightly open the governor oil
passage to drain
allowing the blade counterweight force to move the blades toward coarse
pitch.

Further:-----
One (me) tends to forget that these are not altitude engines so the full
power run-up I have described is subject to variation in engine power output
which, among other things, is a function of field barometric pressure. So,
while I am confident that my description is correct in standard air up to at
least 1200 ft. ASL I cannot confirm it is valid above that.

That would be very true if the propellor was fixed pitch or even a
two-position type.
However this is a constant speed prop. controlled by a fly weight governor
that "knows" nothing about blade angle - only RPM.
Pre-flight (static) check of a correctly adjusted prop./gov. system (CJ 6
with Huosai 6a) with the RPM control set to TO would show on reaching full
throttle slightly over 2350 RPM (+ 15 to 25) momentarily with an immediate
reduction to 2350 as the governor responds.
On take-off as the propellor load decreases the governor senses an overspeed
condition and causes the pilot valve to slightly open the governor oil
passage to drain
allowing the blade counterweight force to move the blades toward coarse
pitch.

Phil, you shouldn't get 2350 RPM on a stationary run up. It will be so
when your plane is moving on take off, when the aerodynamic resistance on
the blades is lessened as the prop is moving forwards.
Try it out and see.
