Gents,
I wanted to thank everyone for the many leads offered to help locate a set of Yak-52
gill shutters. By the time this was over, I ended up exchanging e-mails
with Yak drivers in eight countries. The next person who does the CJ-6A - M-14P
conversion will find that locating a set of working gill shutters will probably
be the most difficult item.
Richard Goode in the UK came through for me. As everyone knows, he is an amazing
resource. Thanks Richard!
Fly safe,

| Subject: | Solid State Ignition (MSD) |
Gents (and one or two Ladies),
I had an idea some time back to develop and promote a quasi solid state ignition
system for M-14 engines. With my background in car engines and my limited experience
with M-14 engines, I saw an area where possibly the two technologies
could come together.
Couple this with the current lack of mag coils for our engine this idea led me
to look into designing and operating a prototype, which in fact I did. I have
decided not to pursue this idea because of lack of time and the fact that I do
not have a very good business sense. I have handed this idea and detailed info
on how to accomplish it to Dennis Savareese, who of course is the original
gent who did all the research and design work on the high performance automobile
ignition system that so many of us have used and value so highly.
I have decided to post this information here for all to use should they have a
desire to, because sooner or later the gist of it will become public and for nothing
else, I would indeed at least like to get the credit for thinking of it
first.
One of the best automobile ignition systems for racing cars today is the MSD (Multiple
Spark Discharge) ignition system. As it turns out, their MSD-6AL system
will run off of 24 volts DC with no modifications. It has only ONE requirement
for 12 volts, and that is the turn on signal that comes in the white wire
and that is very low current. Figuring out how to do that is pretty easy, so
I am not going into it here.
A standard high performance ignition coil from MSD can be used which is powered
directly from the MSD-6AL unit.
The MSD box needs a trigger, which is easily provided by the existing points that
are internal to the existing M-9 mag.
The hookup is pretty simple. Take your right mag out and remove the mag coil.
You now have a spare mag coil. Route the high voltage output wire of the MSD
automotive coil into the mag and connect it to the cigarette stub where the secondary
of the original mag coil hooked to. It is possible to do this by going
through the original P lead input connection on the M-9 mag. Bring the wire
out from the mags internal points anyway you feel like it and hook it to the
trigger input wire on the MSD-6AL system.
Thats pretty much it. You now have a solid state multiple spark discharge system
operating on your right mag, which also happens to be your lower plugs. The
lower plugs tend to foul more often than the upper plugs, and the MSD system
will tend to burn these deposits right off immediately after starting.
The engine will still use the shower of sparks system on the left mag for starting,
but should that fail, you can turn on just the right mag and start off the
MSD system easily.
The MSD system runs off your aircrafts electrical system. Thus should your electrical
system fail, you will lose ignition on your right side.
It would be possible to use this system on BOTH mags, and install a backup battery
for emergencies, but I applied the KISS principle to this original design.
Once you see all the options available, there is a ton of additional things that
can be done with a little imagination.
I am not recommending that everyone go out and do this. It is an OPTION. Something
to keep in the back of your mind. But it works. Ive tried it.

That's a very good start, Mark and I'm glad Dennis is running with it. Just a thought....why
not get rid of
the points at the same time and substitute a suitable sized lobe sensing module
for the trigger and go full electronic ?

Thank you all for the great feedback and insights into the Yak-18T spinner question.
It sounds like the vibration/timing risks can be readily addressed, as
well as the removal/installation time. I see prices quoted from $2200 (all new
GT Propeller design) to $4000 (a new Hartzell spinner for the UTVA-66). Does
anyone have a lead on a source for a "stock" 18T spinner? Or price? I would
think they would run less than the ones cited above. Let me know. Thanks again!
