Uneven engine operation.

[samvear]

Hi all!
I overhauled the D24T.
-put new sleeves, squandered
-installed new Kolbenschmidt pistons
-installed new valves, ground them
After repair, the motor, during operation, sways at a certain speed.

I want to record a video of his work. Post it here so we can diagnose.

But I don't speak English and I won't be able to comment on the video
