Sorry, I have problems understanding what you really say - are you using some translation software?

You may be having trouble with the air injector that take flywheel air and outs it into the air box for the carburetor. Maybe the device is broken and collapses? I once had a 371 do this.

Remove the air filter cover and try to run the chainsaw?

Do you have a known good carb to swap out and try?  I have one here I never did figure out myself.   Thats how I figured out it was the carb by swapping in one off a good runner to test with.
 No matter what I did with the old carb, rebuild, adjustments etc it just flat wasnt right.

I had a Tillotson on a Dolmar that would go rich at high speed and it was the high speed nozzle check valve in the carburetor that was bad.
