The engine in the saw is assembled well, this can be seen even because the saw starts. Always without problems immediately from a half-width. Quietly works even on gasoline that has been in the tank for a month. The main thing is that at idle it smokes a little and everything is fine. I set up a gazebo with her help. It is very convenient, by the way, to saw through the entire beam and even made grooves. The chain is good. Generally satisfied.
