Doug? Anyone!?

Got a few spare carbies here that I'd like to overhaul, preserve and green tag for future use.

Although there are many and surprising differences between the Russian AI14
and Chinese HS-6 engines, the carburettors are identical, and with
Aerometal, our partner in Hungary, we have all the tooling and parts to
totally overhaul these carburettors. Please contact me off-list for more
information.

If you are referring to HS6 (CJ6a) carbs then they are not the same as the m14p unit and the diaphragms are unique to both engines and not interchangeable.

Doug S is always my source of membrane when we change them (we set a 6 year life for this item, better safe than sorry).

I was not referring to the M 14 P carburettor, but to the AI 14 carburettor,
which is identical to the HS-6 carburettor, and therefore we have 40 years
of experience in overhauling them!

By way of background, Ivchenko in Russia developed the AI 14 engine, and the
Russians gave the basic design to the Chinese, along with the Yak 18 A
aircraft. As you know the Chinese changed the airframe radically, but also
made a significant number of changes to the engine to reduce the HS-6. In
the meantime the Russian authorities told Ivchenko that they should
concentrate on small jet engines, and gave the AI 14 design to a new design
bureau in Voronezh, headed up by Vedenyeev who went on to develop the M 14 P
engine.

Thanks Richard that’s also good to know as we only tend to keep one membrane here at a time.

Do they have a shelf life, being rubber (or some kind of neoprene) they must go off even on the shelf.

Officially the six-year "life" is after two years of storage, so if you don't install within two years, the service life reduces. But they are an important item – a few months ago we had to perform a shock-load inspection on the engine of a French 52 whose pilot was flying it when the engine started running rough and then got worse and then finally stopped and so he pulled off quite a good forced landing in a small field, but hit the propeller. The shock-load disassembly inspection and reassembly didn't reveal any internal problems, but we then put the engine onto the dynamometer, and it simply wouldn't run and we realised that the original problem had been the main carburettor membrane!

Hi Richard;

The HS6 engine is history! It was a license built version of the AI14 for
initial production of the Chinese designed CJ6 trainer.

While there are probably a few HS6's floating around, most are HS6A engines
which, other than the basic design (shared by the M14), are internally
different in virtually every respect; EG: Carb. - increased venturi size,
Piston and rings - improved oil control, Blower ratio & rated power, etc.

Some one on this list recently made a very good case that the carb.
diaphragm for the HS6A and M14P (and possibly all other models) was
interchangeable.
Though I have not yet had occasion to confirm or deny I suspect that is
likely correct.

Cheers;
Walt

Yes, as I keep saying, we are not very familiar with the Chinese engines,
mainly because there are so few in Europe. But we bought a couple of them to
dismantle and establish our ability to overhaul them, but sadly found that
they really were quite different in many ways to the AI 14. But one thing we
established is that the carburettor is the same for AI 14 and HS-6A hence
saying that we can overhaul the carburettors and of course supply the
diaphragms. Again by way of confirmation, these diaphragms are also the same
as in the carburettor of the M 14 engine.

Richard

Are the any of the hs6 engines you have complete minus accessories ( either assembled or in bits) and would you be looking to get rid of some or any of them if not rebuilding?

Feel free to contact me off list
