Russian MDS-10KRU first start after 28 years of storage 

Nicely done, sir. Thats how to clean an engine!

Hi, great job on that nice engine! So, I have the same engine, sitting in garage for almost 25 years. Could you please specify what kind of fluid you used for cleaning the engine, the propeller size (and model also) and finally fuel mix you used ? Thanks

Hi just get same engine. Any chance you have pictures of manuals which came with it ?

Great Russian engine. Very powerful and highly energetic, but the valve timing is designed to work with resonant pipes, not with a silencer.
