Hi David! MDS was imported by Robbe, for international market. MAC in cyrillic is the MDS for russian market. As to our experience with slightly worse machining, but still remarkably good running engines. they are a screamer. Check my MDS 60 run in video with an idle of appr. 1500 rpm. the text on the side sais MADE IN USSR (CCCP). Nice catch!
Great information!! Does this mean this was a Russian marketed engine only then? Any idea for a date of this engine? I knew I could count on subscribers to provide more information. Thank you!
@@dmrcflyr2 Actually no idea, because i got it from ukraine for replacement parts and believed i will get an MDS engine. first i wondered wtf, but its really the same. you have the original box, it just had a lid saying MAC
I used to have one of these long time ago...yeah it's rare. The things I remember of it were that it was pretty hard to start and I'd used a little bit diethyl ether, it can go up to 20k rpm and was with short life, something like 25-30 hours or so, it's a bit of a lottery because of the quality of chrome coating, my wasn't good so maybe that was the reason for that short lifespan...as I can remember it was produce from 1970 to 1991 and now there are new production, again from Russia, with good quallity and practically costless for that quallity (20-30 usd) btw at the time when I bought my it costed something like 5 dollars.
I have a mds 60 in a 40 size Spacewalker. It runns great. I did read that the 60 and 40 were made to run on low nitro 5% or less and not for the American market. The 48 and 68 were made for USA and could use 15%. I run my 60 with 10% with no issue. Yeah my key had to be cut to tighten the bolt, I'm not sure what they were thinking there.
1:06 Yes! At first, the USSR made these motors, and then Russia began to produce motors in the city of Tver, Kimry. 171505, Россия,Тверская обл., г.Кимры, ул. Старозаводская, 13 e-mail: info@mds-micro.ru e-mail: cnc@mds-micro.ru
I have a "MAC Racing ening" that has never been run. It has a gold prop drive and a rear exhaust port for a tuned pipe. It also has the flat head screws. I have never run it but it has more compression than anything I have ever seen. Want it? It is a MAC 10
Cool, it seems its a longstroke engine, i used to own a sokol and a mk17, super soviet era engine, they ran on ether, charcoal starting fluid, and castor oil mix. A real piece of shit. These engines were manufactured by school kids 9th to 12th graders as an afterchool program, to teach them metallurgy skills, as a trade.
I love this engine!!!!!

I have got a gold head version of this engine look the same !
Really cool
сделано в СССР = Made in Russia (Союз Советских Социалистических Республик, Union of Soviet Socialist Republics)
Very nice! Thank you!

It would be interesting to see how it runs.
Lots of,negative,comments but they are OK. Mine s reams too.
Hope it runs better than the Yugo , which was a Russian design and a piece of junk ! Should be interesting ! Keep up the good work !
Yugo is Serbian and actually is pretty smooth, don't talk when you haven't got one and when you don't know about it!

More interesting information. So child labor and educational experience.
Were MDS engines always made by school kids or only in the beginning? I've always heard that they varied in quality, that might explain it.
