Like any engine, it's usually about maintenance. Solution: go down the annual checklist.
Look for those air leaks into the intake tubes at both ends, check for
moisture in the wiring harness: no easy way to do any of that but it needs
to be checked FIRST. Use your infrared thermometer to check for "cool" cylinders,
running one mag at a time.
Quite possible that BOTH mags are in need of routine service. Pull the magneto
covers and look for signs of carbon tracking in the distributor cap. Not just
the inside of the cap but along the mag cap sides near the high tension lead as
well (cigarette). Not sure what I'm talking about? Download those maintenance
articles off the RPA store.

Mark,
Your point about the intake tube gland nut seals is right on the money.
We had one CJ that actually had a couple of the seals missing and the
owner chased the problem for weeks. Finally the intake tubes were
pulled and low and behold.....no rubber seals on the end of a couple of
tubes. Pulled all the intake tubes, replace all the seals and
bingo....problem solved.

It is hard to believe it is an ignition issue if it is doing it
on both mags equally bad. You also mentioned earlier that if you leave
it on BOTH mags operating, you can advance the throttle, it pops a lot,
and then seems to run better and work correctly.
Is this true? Can you advance the throttle and get PAST this
popping and then it runs OK?
Try advancing the throttle very very VERY slowly and see if it
impacts how things happen and give a very detailed report of what
happens. Step by step. You simply can't say too much, but you can
easily say too little and leave out an important detail.
To ME, this sounds like the engine is going lean as you advance
the throttle. The POP POP sound is probably the engine going lean and
having some kind of backfire, or pop in the exhaust itself. It just
FEELS like it is fuel related.
If you can just CREEP the throttle forward a tiny bit at a time
and get by this and then when it gets up to a certain RPM it starts
running better, it IS a fuel thing almost certainly.
Two things... take a VERY VERY close look at your intake tubes!
If you have an intake drain kit, make darn certain that all those lines
are good and there are NO LEAKS! When the engine is at idle it is
drawing a vacuum and as you advance the throttle, if you have a massive
leak, you will draw in fresh air, the engine cylinder will go lean, and
it will POP. Once you get past that a bit, you will develop more
positive pressure in the tube and it will start to richen up and fire
because of the blower.
These are all wild ass guesses based on just my own past
experience with intake leaks on a number of different engines. I mean,
look CAREFULLY for any kind of intake leak. Flange nuts, joints, big
cracks, splits... I mean look CAREFULLY!
Second... it might be something really bad wrong in the carb.
A lot of people are more expert than me on this kind of problem.
However, the more details you can give will end up giving you more
accurate feedback. They are not there, they can not hear or see what is
happening, so it is all on you really.
One clue to me is the manifold pressure bouncing up and down
when it starts popping. This is to me an indication of an intake
backfire.
But all this could be totally wrong.
Mark Bitterlich
p.s. A very dangerous trick to find this kind of thing is to
have the engine idling, and then using very very quick and brief shots,
squirt in some starter fluid around intake areas where there may be a
leak. If you have it at idle and all of a sudden the sound of the
engine changes, you have an intake leak right there. A lot of people
use WD-40 instead to do this, which is not quite as dangerous. I am not
saying you should do this, as it is possible to cause a disaster in the
process. Starting fluid is ether and man oh man... you are literally
playing with fire. I have NEVER done this on an aircraft engine.
NEVER! I have done it on car racing engines, and they are a lot safer.
In any case, I would NEVER use the starter fluid idea on an aircraft
engine, just too damn dangerous. WD-40... maybe.

It is hard to believe it is an ignition issue if it is doing it on both mag
s equally bad.- You also mentioned earlier that if you leave it on BOTH m
ags operating, you can advance the throttle, it pops a lot, and then seems
to run better and work correctly.-
-
Is this true?- Can you advance the throttle and get PAST this popping and
then it runs OK?-
-
Try advancing the throttle very very VERY slowly and see if it impacts how
things happen and give a very detailed report of what happens.- Step by s
tep.- You simply can't say too much, but you can easily say too little an
d leave out an important detail.-
-
To ME, this sounds like the engine is going lean as you advance the throttl
e.- The POP POP sound is probably the engine going lean and having some k
ind of backfire, or pop in the exhaust itself.--It just FEELS like it i
s fuel related.-
-
If you can just CREEP the throttle forward a tiny bit at a time and get by
this and then when it gets up to a certain RPM it starts running better, it
IS a fuel thing almost certainly.-
-
Two things... take a VERY VERY close look at your intake tubes!- If you h
ave an intake drain kit, make darn certain that all those lines are good an
d there are NO LEAKS!- When the engine is at idle it is drawing a vacuum
and as you advance the throttle, if you have a massive leak, you will draw
in fresh air, the engine cylinder will go lean, and it will POP.- Once yo
u get past that a bit, you will develop more positive pressure in the tube
and it will start to richen up and fire because of the blower.-
-
These are all wild ass guesses based on just my own past experience with in
take leaks on a number of different engines.- I mean, look CAREFULLY for
any kind of intake leak.- Flange nuts, joints, big cracks, splits... I me
an look CAREFULLY!-
-
Second... it might be something really bad wrong in the carb.-
-
A lot of people are more expert than me on this kind of problem.- However
, the more details you can give will end up giving you more accurate feedba
ck.- They are not there, they can not hear or see what is happening, so i
t is all on you really.-
-
One clue to me is the manifold pressure bouncing up and down when it starts
popping.- This is to me an indication of an intake backfire.-
-
But all this could be totally wrong.
-
Mark Bitterlich
-
p.s.- A very dangerous trick to find this kind of thing is to have the en
gine idling, and then using very very quick and brief shots, squirt in some
-starter fluid around intake areas where there may be a leak.- If you h
ave it at idle and all of a sudden the sound of the engine changes, you hav
e an intake leak right there.- A lot of people use WD-40 instead to do th
is, which is not quite as dangerous.- I am not saying you should do this,
as it is possible to cause a disaster in the process.- Starting fluid is
ether and man oh man... you are literally playing with fire.- I have NEV
ER done this on an aircraft engine.- NEVER!-- I have done it on car r
acing engines, and they are a lot safer.- In any case, I would NEVER use
the starter fluid idea on an aircraft engine, just too damn dangerous.- W
D-40... maybe.-

Hi Gang,
We've been over in the Bahamas now for 6 weeks and just when you think it
can't get any better than this.... a couple of CJ-6's make a beautiful lo
w pass the yacht! Don't know who you guys were but if you're on the list,
well done! Saw you again today (16th Friday) heading back north to Nassa
u.
I haven't taken my Yak 52 over to Bahamas. Does anyone on the list has an
y info regarding bringing a experimental exhibition plane into Bahamas?
Any special requirements into the islands or different requirements comin
g back into the USA other than the usual flight plan, Homeland security co
