If it is difficult to start a cold engine, it is necessary to adjust the starting clearances of the air and throttle valves of the first chamber.
1. Turn the choke control lever fully counterclockwise and hold it in this position. In this case, the air damper should close completely.
2. Use the blade of a screwdriver 1 to sink the rod 2 of the starting device as far as it will go. This will open the air damper.
3. Check the gap between the bottom (in the direction of the air) edge of the air damper and the neck wall by inserting the drill shank into it (or caliber) 2.2 mm in diameter.
4. If the gap is larger or smaller than the diameter of the drill, adjust it by loosening the locknut of the starter stop screw and...
5.... by turning the screw with a screwdriver. When the screw is screwed into the cover of the diaphragm mechanism, the gap decreases, when unscrewed, it increases. Tighten locknut securely after adjustment is complete.
6. Without releasing the choke lever, turn the carburetor with the throttle body up and check with the drill shank (or caliber) diameter 0.8 mm gap between the bottom (in the direction of the air) edge of the throttle valve and the wall of the first chamber.
7. If the gap is larger or smaller than the drill diameter, adjust it by turning the adjusting stop screw screwed into the throttle control lever. When the screw is screwed into the lever, the gap decreases, when unscrewed, it increases.
