For the Yak 52 guys, the QS-1 valve on the CJ6, which I believe is
located in the center belly of the CJ fuselage inside the large
inspection panel, is exactly the same as the Yak 52's brake reducing
valve located in the rear cockpit under the floor panel on the right
side of the control stick. The parts are interchangeable. So if your
52's brake reducing valve goes T.U., and you can't find one from the 52
parts suppliers, try our good friend Doug Sapp.

what/where is the "QS-1" valve?

somewhere in the belly. I traced it to the QS-1. I replaced it with
one I already had on the shelf. Bingo problem solved. Test flight with
some acro thrown in, showed all back to "normal".
I can replace the rubber seal in the valve and the steel springs
inside and she'll be put on the parts shelf, well oiled and greased in a
baggy.

You dont have to replace the valve,overhaul with new seals from Sapp. Cost
is 12$ for the QS2.
very easy to do.

Dennis and all,
The QS2B is the very latest version of the QS2. Used in CJ's 2000 and
later year models. I have not had a reason to pull one apart yet but
they look like a somewhat improved version. Bolt up is identical.
Also, just got in a shipment from China which has a few landing lights
in it. First come first served.
1.. Landing light bulbs
2.. QS2B diff brake valves
3.. nose wheel tires and tubes
4.. Main air tanks
5.. Factory new 285 hp carburetors
6.. QDF-1 start solenoid valves
7.. GKY-5 heated pitots
8.. BYQ80-1A air pressure gauge
9.. Main wheel assemblies
10.. QSF-6A main and emergency air valve
11.. Nose gear incline brace
12.. Brake drums
13.. Brake pads
14.. New cowling
15.. New wing panels L&R
16.. New ailerons
17.. New main gear legs
18.. New J9-G1 propellers and blades
19.. New V530 blades
20.. Manifold pressure gauges
21.. 3/1 gauges
22.. Yak an CJ heavy insulated cowling blankets
23.. Wing walk roll (allows mechanic to walk on right side of stub
wing/fuse without damage)
24.. Lower and upper gear door hardware
25.. Oil tanks
26.. New rudders
Please give me a call @ 509-826-4610 or contact me OFF LIST.
Always Yakin,

Dennis,
We've done all tests/run-ups on both mags and each mag separately
with identical results. I did pull the cap on the left mag and checked
everything that you mentioned below and checked out good. It would have to
be spectacular luck (good or bad your choice of words) to have identical
ignition failures on both mags at the same time or to have the time go out
the same amount. Unless of course, there is some form of crossover I am not
aware of. Thanks for the advice though.

You did not say you tried isolating the problem to one mag or the
other? Have you looked inside the magnetos under the mag caps and checked
for adequate lubrication on the cam? Also look for obvious binding at the
points. Verify the point gap is between .25 mm and .35 mm or .010 to .14.
Ideally, .3 mm or .012. Look inside the mag cap for carbon tracks. Gary's
suggestion is also very sound and highly recommended. Check the timing on
both mags. Let me know what you did or found.

Have you checked the spark plug leads with a high tension lead
tester, it sounds like the leads may be breaking down under a load... Gary
-------------- Original message from "Scott T Glaser (E-mail
2)" <shinden33@earthlink.net>: --------------
Thanks for the advice guys. I've tried everything short of
installing the plug kit. I'm not sure that's the issue.
The roughness seems to be getting worse & I did discover
using a laser thermometer and the WD40 test that the #5, 7 and 9 cylinders
seem not to be firing. We measured the temps of the exhaust stacks just
after shut down and all were 220+ deg except those three which were 112ish.
We also did the WD40 test (sprayed WD40 on the exhaust just aft of each
cylinder). Again it showed that these 3 cylinders were not operating
properly (WD40 did not vaporize). I have pulled and checked all the plugs,
checked the left mag (another suspected problem), checked all the wires,
checked the fine fuel filter, checked the carb fuel filter, compression
checked all the cylinders (all 69+/80) and have not found the problem. I've
consulted with local mechanics who seem to be out of ideas. I'm about ready
to call in an M14 mechani c.&nbs p; Let me know if anyone has any
suggestions.

The fine fuel filter is the black canister above the
yellow sphere on the right side of the firewall. On the bottom side of the
black canister is a 27 mm nut, usually safety wired. Remove the 27 mm nut
and extract the fuel screen. It will be a little tight coming out. Clean
the screen with a tooth brush and be sure to inspect the inside of the cap
you removed for debris. Make very sure the small rubber O-ring is on the
top end of the screen when it comes out and when it goes back in.
The American Champion REL37B's are not the plugs in the
conversion kit. If you'd like to read about the conversion kit, go to my
web site, www.yak-52.com, and click on the MODIFICATIONS button, then click
the PLUG CONVERSION button. Or click on the link on the home page. By
comparison, the plugs in the conversion kit will cost you about $2 per plug
when you have to replace them. ONE Champion REL37B will cost almost as much
as 18 plugs. The kits have been shipped all over the world and I have kits
in stock.

Suggest you also check the fine fuel filter and clean
if necessary. The spark plug conversion is definitely the way to go
regardless of this problem.
