Hello. I have a problem with starting the brush cutter. I wanted to find out the designation of the suction in the drawing and what are the two screws for because I have one more screw to adjust, but it is idle. Thank you in advance for your help. greetings

The choke is switched on in position 1 and off in position 3. These screws are used to adjust the carburetor, L is idling and H is the maximum. The third one is a throttle stop screw. On 1, only a cold engine is fired, until the first reaction, then switch to 2 and start (cold engine) or 3 warm. A warm engine should start on the 3rd.

Thanks for the answer. Because I have these two and one more marked + and - so sometimes it will not idle? greetings

Add that they regulate the composition of the mixture, not just the turnover. An amateur better not turn them ...
