John,
Since new I have added two pints of Av-blend oil Treatment to my MP-14
Engine every oil change (Phillips 66 XC 25/60) tack now at 961
Hours.Last Inspected for condition FAR 43 appendix D lowest clynder
comprestion check 77/80 oil consumption 3/4 of a qurit per hour.

You're absolutely right Walt, but to be fair ... let's compare how many tim

Doc,
You seem to be real "special" when it comes to shit happening! =C2-
I'll keep this brief and do encourage the listers and lurkers to respond on
the subject.--- In over 20 years of using and selling Chinese spark plugs
I have NEVER, repeat NEVER seen or heard of a Chinese DZ5 plugs blow out th
e centers. =C2-Are you 100% sure that you are not confusing them with the
Russian plugs which=C2-unfortunately=C2-do have a reputation for blowi
ng out the ceramics?? =C2-All that said, if ANY plug, of any mfg has been
dropped all bets are off and it should be treated as very suspect and IMHO
should not be used.
I personally have not seen the need to do the auto plug mod yet, but when i
t comes time to start replacing leads I too will do the auto plug mod, but
at this time my=C2-ignition=C2-harness seems to be good. =C2-It would
seem to me that if all you guys who are running the auto plug conversion w
ould report in as to which wire and which plug you are running (and if you
have seen any problems) the correct combination of plug type and wire type
would soon be=C2-obvious. =C2-

Craig,
I have had the same problem with Ru and Chinese plugs in the 52 with its
=99 M-14. It was a bad capacitor in the Mag Coil. Replacing the coil sol
ved the problem. It occurs 20 min into the flight with an abrupt Kaahoop an
d the blade stops a tick due to the misfire. You can almost set your clock
to the heart stopping misfire. I think you fixed your problem by swapping o
ut your mags with the bad coil. You hit the nail on the head with your thou
ghts about over heating the coils but I seriously doubt it was the plugs th
at did that. I have the NGK plugs in my 50 =C2-without the problem to dat
e. I have had the problem in the 50 also with a bad coil causing a discharg
e with the ensuing misfire. That occurred with the existing Chinese plugs n
ot the new NGK=99s. I changed the wires and plugs a little later when
I blew out a couple the Chinese plugs (the ceramic core cracked and the pl
ugs broke down). So I changed the plugs to the NGK=99s and did the pl
ug wire
conversion. That led to a different problem with RF interference. That is
another story for another setting.

Subject: Yak-List: Automotive Plug Alert
When using automotive plugs in either the Huosai or M-14 type engines, you
MUST use the resistor type plugs as the non-resistive type may conduct an e
xcess amount of current, overheating the magneto coils, leading to rough ma
g operation.
=C2-
While discussing teething problems in the latest modified M-14P engine with
a fellow RedStar, I realized that I had encountered the same problem 3 yea
rs ago but never quite made the connection to overheating of the coils. My
situtation caused me to assume bad mags. After working my way through the p
ile of mags I have, I lost track of my troubleshooting thread and switched
spark plugs to the NGK BRxHS motorcycle plug and my problems went away. Whi
le I wasn't sure what caused the problem to go away, I shelved the mags and
haven't changed much since.
=C2-
My problem showed up after 10-20 minutes of operation but in another airpla
ne the problem occurred just about 50 minutes into the flight. Currently I
have moved from the #6 plug to the hotter #5 plug to better match the way I
operate at the Cruise II setting. For higher power settings, I would go ba
ck to the BR6HS.
=C2-
Now I'll go back through the pile of mags=C2-and test a bit when I get th
e chance.

Subject: Yak-List: Re: magnetos
One of the problems with the Chinese and Russian Magnetos is the placement
of the capacitor within the coil.- The coils run hot which degrades the c
apacitor.- If one looks at the Mallory Super Mags and Sprint Mags the coi
l is outside the magneto.- Looking at the top Fuel dragsters and Funny Ca
rs the MSD Magneto coils are outside the magnetos.- When ever high curren
ts and coils are involved heat is an enemy.- Eventually even the Vertex M
agneto was available with an external coil.- The Taylor Plug wire used in
the auto conversions is not really a resistor wire but is a spiral wound w
ire which somewhat defeats the unwanted radiated RF energy, due to the use
of finer wire and the spiral winding adding to the effective wire length th
e resistance is higher than the Russian of Chinese wire.

Don, thanks for your post.- I have heard across the board good comments a
bout this product but was somewhat hesitant to try it myself.- I am a die

I Microlon all my engines .... on my autos I see a 10% mpg
improvement. I don't know what it will does for my M14PF, but the
test results on various engines are consistent with my own results.
http://www.microlon.com/engine_treatment_test_data.php
This is a one time treatment .... you don't need to add anything to
your oil after you do the treatment.
