Unfortunately, there are no safe places in Ukraine now.

It sounds to me like the injection pump timing may be set incorrectly.
I have tried different options for setting the injection timing. 0.8; 0.85; 0.9; 0.95mm
With a smaller value, the motor runs softer. With a larger value - works hard.
However - at any value, the motor staggers at about 1400 rpm.

And, did you remember to disconnect the cold start device cable when setting the timing? Easy to forget this, and if you do, it results in retarded injection timing that leads to issues like what you are seeing.
I turn it off during setup.

It sounds like it starts right away...
Yes, the engine starts immediately(right away). Both hot and cold.

Perhaps somewhere there is a video on how this motor should work correctly ... I have nothing to compare with.
