An amazing place!
As if in Soviet times, they were guided by acquaintance to the engine repair shop, directly to the craftsmen.
Not from the first visit, I learned that there is a full range of services here - washing the engine in the chamber, grinding the crankshaft, boring blocks, crimping and grinding the cylinder head, and brewing is also not a question.
Then it turned out that they could stupidly bring a faulty motor and then pick up a serviceable one.
