An HS-6A will hand prop with mags on without using the start button/shower of sparks...
and the engine does not need to be hot. Not SOP, but something to respect
when moving the prop.

Ok all, looking for additional tachometer advice...
In yesterday's flight, I noticed both front & rear tach gauges were
intermittently erratic.
Both gauges read the same fluctuations (thanks to my backseat pass. giving
updates as requested).
I've recently & thoroughly cleaned the Chinese-stock tach generator & front
gauge's cannon plugs and reinstalled securely.
Both the tach generator & front gauge are only 5 yrs old, all stock Chinese.
Before I dive into the schematic & wire bundles, anyone hit this gremlin
before?
Culprits to start looking for?
Successful experience stories appreciated!
Thanks,
Justin Drafts

Justin,
Try some dielectric grease in the cannon plug before you do anything else. Worked

Yes, I have run into this before Justin but that said, I have no experience on
CJ-6's so I have to make a few assumptions, one being that the design is close
to the M-14. The first place to look is the tach generator cannon plug,
On the M-14 the wires are soldered into the plug, and due to vibration those solder
joint fractures. Carefully inspect and re-solder the wires into the solder
cups in the plug and be especially careful with shielding. If the shield
to those wires loses ground, you will have the worst radio noise imaginable,
in fact so strong it burnt out the AGC stage in a stock Russian VHF radio.
Mark
p.s. Nothing wrong with trying some dielectric grease either as Dan suggested.

Indeed. How about being respectful enough to sign your posts with your real name?
Anonymous postings that attempt to correct what others write with no references
and no name are worthless.
You said: "SURE ! you can start many engines by spooling it up to 80+% and then
flipping ignition switch. is that SOP ? NO ! read the original manual instead
of arguing."
There is no "universal manual" for all aircraft that have M-14's mounted or use
-35M mags. And I know of no electric starter that spins an M-14 at 80% . However
I do know of two aircraft that have an M-14, electric start, -35M mags,
and simply unground the P lead to start their engines. The person writing the
original question has a 52TW, and some of those had electric start, some had
pneumatic, and you can even have it with both. Is that in your manual? You're
the one arguing, I'm simply stating useful to know information, but I do admit
to becoming annoyed at your responses that offer nothing of value to anyone,
but then I suspect that is your intent to begin with. Otherwise why the
continued refusal to sign your own name, even when asked? How about the "N"
number of the aircraft you own ?

i wanted to stay out of but you just keep going...
what "useful to know information" you are stating ? that it's ok to rotate the
engine and then
"simply unground the P lead " ? you never heard about M-14P with M-9F kicking back
and reversing rotation because KP-4716 did not engage to spool it to sufficiently
high RPM ?
doesn't M9-35 magneto still have 25 deg. advance below 800RPM ? you know what
such reversal does to electric starter and gear ring teeth ? can show.
why those russians mounted PK-45 ignition unit there if you can "simply unground
the P lead " ?

FACT- The Russians never did it. It was aN afterthought creation of the Aerostar
factory back in 2000 when they decided to build the Yak52TW, which was essentially
a US design to begin with.
People were having difficulty starting the TWs with PF engines with -35 mags. They
were trying to start them like a stock 52 with M9F mags. That didnt work.
Once they figured out how to properly start the engine with -35 mags, the p-lead
booster was irrelevant.

yes, i'm intrigued. so since 70's russians were starting these engines with -35
mags "improperly" ? and in 2000 someone figured out how to do it "properly"
thereby external
ignition exciter is not needed ? so, there's no such unit on 52TW since it's no
longer needed ?
i'm just trying to figure out what exactly your cryptic message says. any reference
to
or a description of this "proper" start procedure ?

Mr. Anonymous with no name says:
>"what useful to know information" you are stating ? that it's ok to rotate
the engine and then simply unground the P lead ? you never heard about
M-14P with M-9F kicking back and reversing rotation because KP-4716 did not

Yes, I have heard about that. That is why you start an M-14 with M9F mags
with the mag switch turned off. But .... Last time I checked, I was
talking about -35M mags. You know, the ones that only have one rotor point?
The ones with centrifugal advance?
>"doesn't M9-35 magneto still have 25 deg. advance below 800RPM ? you know

I think you are somewhat confused regarding how -35M mags work. The timing
at initial start on a -35M mag is the same whether you simply unground the P
lead, and rotate the engine, or if you pulse the -35M internal coil and
rotate the engine. I assumed you had the manual for these mags.
>"why those russians mounted PK-45 ignition unit there if you can "simply
unground the P lead " ?
Because the Russians used pneumatic start exclusively which is well known to
spin the engine very slowly, especially when hot, and when the air bottle
runs low. You will notice that every time I talked about this method with
-35M mags, I mentioned a number of M-14 equipped aircraft with ELECTRIC
START. The electric starter spins the mags fast enough for the mag to fire
the plugs without external excitation.
It is a useful thing to know, and it is not in any Russian manual, hence the
purpose of the Yak List. To share experiences, observations, and things we
all have learned. For others it offers a different opportunity.

I'm going to make pubic a feeling I have regarding this gent.
Anyone who refuses to give their name on the Yak List should be totally ignored.
Enough is enough. This gent is a troll, and should be treated as such. He takes
pleasure in stirring up bad feelings. There have been many arguments and debates
on the Yak List, and I personally have been involved in more than one,
but I never did it while refusing to identify myself and neither has anyone else
I can remember, right/wrong/indifferent.
