Super interesting thread. Looks like it's been dormant for a while. I only came across it because it was linked in another thread.
But this is the first up close look I've had at the old Russian "D" series engines. Nice looking stuff.

Is D-series engine really superior to modern chinese analogs(copies)? Manual of original D8 engine says about 1.1 hp at 5000 rpm using A-76 soviet era petrol. Possibly, chinese manufacturers make some changes to increase output (I've never had one). Production quality of original motors also raises doubts. I think, only some antiques collector may be interested in things of this sort.

Howdy Klim. Welcome to the forum.
Buried in this thread, some where, I researched and found one company still make the motors. But they are used for pumps now. I would love to have one. This was at least 2 years ago and they would cost around $300 USD to get to the U.S. Big bummer.
But again, welcome and glad to see you.

Klim does bring up one good point. Welcome aboard, by the way, Klim.
Can we be sure that the Soviet era D series engines were of a higher quality than the current Chinese copies?
(I can hear it now......."How could they be worse?")
I really like the look of the D series. But, in truth, it doesn't exactly look like a Rolls-Royce engine.

Har, lol! "How could they be worse?"
Really did. Was putting a cough drop in my mouth and went "pFFFEFTH" and spit on it laughing.
I bet "cough drops" do not translate well using google to any other language. And would cause the question; "It is a drop of cough, and you put this in your mouth?"

Hello, guys, thanks for welcoming me... 
"Krasny Oktiabr" (Red October, http://koavia.com/e_index.htm) was big Soviet concern (as you already possibly know), situated in Leningrad (St. Petersburg now), that produced throughout its history wide range of machinery (mainly military) - aircraft, helicopter, tank, tractor engines and parts, swashplates, surface-to-air missiles etc. The plant that made D-engines is its consumer branch and situated in backwater town of Borovichi. I can not even find their website in RuNet - only address and phone numbers. See some photos (were found in one russian forum) – made year or more ago, everything looks rather dilapidated. Most likely the plant has long ago gone bankrupt. Or makes some secondary components for parent company. Another non-military subsidiary exists until now - "Krasny Oktiabr - Neva"(someone has mentioned it in this thread), produces tillers utilizing imported engines (Honda, Briggs&Stratton etc.) as powerplant. It was common practice for big military soviet enterprises to have some consumer production.
My doubts concerning quality ensue from knowledge that by 1980-90ies manufacturing and discipline standards had gone pretty slack at least in soviet civil production lines. Circa 1991, being schoolboy, your humble servant got job as apprentice in the enterprise, manufacturing fighter turbofan as main product. Civil branch, where he was employed made high performance tiller engines (output 5 hp, weight over 50 kilograms
). Patriotic youth as he was, he had all possibilities to observe that favorite pastimes of line staff during dinner breaks were drinking (cough drops ) technical grade alcohol and stealing pistons, which abovementioned high-end tiller engine shared with some ubiquitous automotive one.
By the way, turbofan line still exists (under defence ministry protection), tiller line was closed (I suspect Honda Co had a finger in the pie, eliminating dangerous competitor).

It's seems like D6 engine, because the high voltage wire exits the ignition chamber.
In general, all of D engine I made a good ignition voltage converter and the ability to get a powerful light. About all this is on the site wagnerland.ru, which was mentioned in the same topic before.

I found a historical engine, but unfortunately he did not complete, but the originals
Hello. I think that the fastest you can find spare parts in Russia or in Ukraine. Sometimes it can be found in Hungary.

Many owners of motor "A" practice installation of electronic ignition,

and can be easily installed on the ignition of the Chinese F-50 (80).
Motor D-8E is different from the motor D-8M presence of external ignition coil.
