| Subject: | Auto plugs up high |
For the density altitude reason that "Pappy' mentioned, I believe the gap on auto
plugs be limited to .025" when installed on the M-14P or Huosai with standard
mags. They seem to feel smoother at altitude in my experience.

I don't think there is any correlation between the plugs and wires and
misfires at high altitudes. The occurrence of high altitude misfires is
typically due to arc over inside the magneto. On the ground the arc occurs
in the combustion chamber in the spark plug. The gap is set so that under
pressure this is the most likely place for the arc to occur. As you go up in
altitude the pressure inside the combustion chamber stays relatively the
same, but the air pressure inside the mag gets lower and thus it is easier
for an arc over in the mag to occur. Airplanes that fly to higher altitudes
have pressurized magnetos and ignition systems to keep the most likely place
for the arc to occur in the combustion chamber. Another thing to do is to
keep your plug gap at a minimum, typical plug gaps are 0.016 to 0.021 inches
and if you fly at high altitudes you want to check your plug gap more often
and set it to the smallest end of the range.
Squatch out.

Dennis,
Are their any problems with the automotive plugs at high altitude ie: 18K+?
Any of your customers routinely fly them this high?

Hi Listers, I have purchased a Yak 18t, soon to be flying, and thought I
would investigate suitable noise cancelling headsets.
There a few available and would be interested to get your
recommendations as to which model to purchase that work best at reducing
the noise (inside the cockpit), at the frequencies produced by the M14P.
Cheers, Phil Gower.
