Well done! But of greater general interest is whether anyone can confirm that either
new or overhauled engines are currently available from China? Doug Sapp
seems to know everyone relevant and his view is that no engines are available!

Given that the HS-6 (not the A), is effectively the AI-14, how big a step would
it be to uprate one to 285hp A spec? From the little research Ive done, it seems
the only real difference is the carb.

| Subject: | Re: HS-6 engine needed |
According to the Russian documentation that I have, the HS-6 is "a Chinese version
of the AI 14 R", which was the original Russian production engine of 1956,
nominally 260 hp. Then they say that the HS-6A is a Chinese version of the AI
14 RF. This was a higher performance version, principally aimed at the Yak 18
single-seat aerobatic aircraft, and which delivered 300 hp. However they go on
to say that this extra horsepower was developed only through increased rpm rather
than any other modifications.
I would be confident that an AI 14 adjusted to turn at around 2550 rpm (as opposed
to the very modest standard maximum of 2350 rpm) would certainly produce 285
hp. Also they had very generous tolerances for the supercharger clearances,
and we have found that by decreasing these tolerances, it is easy to obtain an
additional 15 or so horsepower in itself.
And of course these rpm figures are significantly less than the 2950 rpm (101%)
which is the maximum for the M 14 P engine, of course essentially the same, albeit
modified and strengthened.

I have one Housai engine that should be a good engine. It was purchased
from China by my father as a zero time since overhaul. When it arrived, it
was obviously not as presented. We assumed it was a + or- 600 hr. Engine. I
have no logs or history on the engine, so it is being offered as is. It has
mags, but no carburetor. We were going to the automotive spark plugs
ignition. It has been stored in an enclosed hangar, and I am offering it as
is, where is, for $3,000.00. I will palletize it and deliver to shipping
company of your choice. Contact me at marcusbates@att.net or call
512-699-5455.

Thanks Richard.
On that note, would turning up an A be feasible?
Im currently discussing retuning our current engine as it runs very cool. Its very
rare to see more than 170C CHT so Im assuming its stock tune for 70+ octane
where we obviously run 100LL; so advancing by the timing seems the way to go.
Can I safely turn up the max revs in your opinion? 2550 on 6A should easily yield
a good 300hp but at what cost?

Interesting you mention the running cool issue (which isnt good, although not as
bad as running too hot) as out of the box mine ran too cool also and I put this
down to the Chinese running them on really crap fuel ( I dont recall the exact
banding but its recorded in my logs) and as such then going into 100LL simply
sees the stock hs6 running too rich. Ive some hadthe carb adjusted and it
seems happier with the added bonus of less fuel bur

I think your over feeding it!! Ideally you should be burning 13.5 to 14.5
GPH at cruise.
That may go a long way to solve your cool engine problem.
Have you ever checked to see what jets you have in your carb?

Loose cylinder base nuts are Much more common on the Huosai than the M14. M14
manual specifies dry thread torque too.
