This diaphragm is for the M14 carburetor. It will not work on the
Housai carburetor.

The tainted fuel absolutely destroyed the carburetor diaphragm. The
symptoms you describe are exactly what I experienced. If you find a source for
replacement diaphragms, please post this information to the list as I cannot
find a source for them any longer.

Will the YAK 52 diaphragm work? If so check with west London Aero Club. They have
them advertised on their website.

No, unfortunately, the M14 carburetor diaphragm will not work on a
Housai carburetor. I did a test several years ago before our friends
in the UK had new diaphragms fabricated. I 'borrowed' a diaphragm from
Doug and tried it. What I found was some of the holes in the M14
diaphragm do not exist in the Housai diaphragm.

I also know that Mark Jefferies in the UK was having new diaphragms
made. No disk in the center. All one had to do is transfer the disk
from the old diaphragm to the new one.

George is right.
Whether you decide to use Mogas or Avgas (or both), the carburetor
diaphragm 'have a life' [Laughing]
... and it will eventually need replacing.
Should be inspected on a regular basis ... or like some people do ...
wait until carburator starts dripping after shut-down.

After some more runups and a little more reading I do believe it is the car
burator diaphram. Doug is out of them. The only place I found was an adve
rtisement for parts on the barnstormers website directly from China. I am
getting way over charged but I don't really have a choice. I'll let you kn
ow what happens.

The symptoms you describe are exactly what I experienced. If you find a so

Pappy said 240 Mph but did you mean 240 KMph?
240mph is nearly 400 kilometers per hour and (aside from being nearly impossible)
is just too fast in a Yak 52.

Assuming Pappy listed wrong units or else that pilot was doing 10% over VNE and
you are working hard to make a Yak 52TW do that, and parts departing would be
the expected result.
Had a little too much of airplanes going over VNE and losing trim tabs in the last
few years... It happened again to another airplane at Reno this year.
Pappy's point remains, check the trim tabs carefully, they prone to getting smacked
back there.

The range markings on all the Westernized Yaks are dubious.
Compare the oil temp limits in the W to the "book" and they are way off in the
ones I flew. Same with ASI
That ASI says your VNE is 450KmPH which is nearly 100KmPH more than the VNE for
a Yak 52. Note the correct Yak VNE is 223mph which corresponds to the beginning
of that ASI Yellow Arc.
Yak 52 Tech Description says 360
Yak 52TW Tech Description says 360
Yak 52TW Flight Manual says 420
That installed Airspeed says 450
Beware translations in Yaks
YMMV..

My YAK-52 doesn't like much above 360-370 kph. Kind of like a T-28 being
pushed above 300 kts. Redline was 340 as I recall. Joining the 300 Knot
Club was where I first heard the saying "Shakin' like a dog shittin' peach
seeds". Just because the gauge says you "can", doesn't necessarily mean you
"should" go there. (Excluding of course jobs for the young and fearless
where taxpayers pay for airplanes with armed ejection seats!)
