The resource is a year of infrequent use: first, the bracket for attaching the protective cover burst. Then the starter broke - inside the plastic axle, it was worn out and broke. And the final blow is the wedge of the engine during operation. There is no longer a guarantee, I opened it myself. Outcome: the roller bearing on the side of the connecting rod shaft shattered inside, its fragments fell into the combustion chamber, the pins were scuffed. Fragments of the bearing were in the muffler.
