Well tried to head south from DE to FL yesterday. After a :45 delay trying to get fuel and oil at ILG, I finally blasted off. Just about 10 minutes at cruise, my M-14 started running rough. At first I thought it was carburetor ice, but heat didn't clear it. Temps, fuel and oil pressures were normal. I turned around back for ILG but than saw a airport at my 9 landed there. Wife was able to drive a pick me up. Today I start to find out what's wrong. After yaking (no pun intended) with Lefty I'm thinking a stuck valve and will pursue that direction first. Also plan on changing out all the plugs.
Most likely will get rained on today.

Hi.
Good to see that someone has seen the same thing, bet it started like this, run ups ok, on roll all was ok but if you put in full power it improved ? this recently happened to me in my 52 and after meggering leads and al basic tests i was convinced that it was valve (after return checked all cylinders with IR gun), but the little voice in the head that comes from years of drag racing experience told me to keep basic, after cycling and spot heat testing i found the problem. It was a small collection of water in the lower plug leads that would only short out when the temp was enough to let a small amount run into the plug cap thus when the plug was removed for inspection your fingers and atmosphere would dry it out just enough to do the cycle again, the fix was undo all the seals get engine hot and allow to dry then reseal the harness.
hope this helps

Chris,
Do you have the plug and wire conversion kit on or do you still have the RU harness and plugs? With the Taylor plug wire and auto plug conversion you are getting water under the plug cap? I can see moister leeching in along the wire bundle as they enter the distributor cap cover but I suspect you have to be flying through some pretty heavy precip for that. At least that is my theory. Have not ops tested it that theory though.

DocHave RU harness and plugs and have problem solved, the cause of the problem was after an annual i cleaned the oil off the back of the engine with kero and a hose which in turn because the OEM harness was not totally sealed it leaked a very minuscule amount, have now dried all out and resealed the rubber compression seals in the oem harness (coincidentally it killed two plugs in the same cylinder '5') the main point of reply was bring attention to the simple things as you also suggested.
thanks,
Chris

Chris,
The Russian wiring harness is the Achilles heal of the M14 ignition system. What Doc is referring to is the automotive conversion kit that I have supplied to the community for several years and he has installed on his Yak 50. http://www.yak-52.com/plug_conversion.htm. Fits both the M14's and Housai engines (wiring harness on the Housai engines is identical to the M14).
The problem you've experience is very common because the braided shielding on the plug wires is porous which permits oil and moisture to not only penetrate the braid, but deteriorate the rubber around the plug wire which is inside the shield. Once the deterioration starts, it only gets worse. The rubber begins to crack and the plug wire arcs to the shield, which is grounded, causing a misfire. FWIW, moisture can not penetrate the caps which connect to the plug wires on the automotive conversion kit.
If I can be of assistance, contact me off-list.
Dennis

Taylor does not make the plug wire conversion kit. Taylor custom manufactures the wires for me that are included in the automotive conversion kit I offer. Contact me off-list for further information.

Dennis,As far as i know we in australia cannot use the auto conversion (even though i would prefer this as this problem has been there before thus short term fix is a little smear of dielectric grease to seal) as our aircraft are Australian vh registered not experimental and need approval thru ad's etc to fit these kits.
Thankyou
Chris

Hi Chris,
The 18T and all the Sukhois are also certificated in Europe and we have obtained full EASA and UK CAA [for other,non-certificated Yaks] approval to fit the kits.
You are a lot more free in these matters than Europe,so surely no problem to get CASA approval.

In addition, I have shipped several kits to individuals in Australia. Based on that, I'm assuming it is acceptable to install the automotive conversion kit.
