If the carburetor cap is replaced or the engine does not respond well to gas supply, the choke gap must be adjusted. In this case, the engine must be warmed up.
Remove air filter.
Use the choke rod to close it as far as it will go -A-.
Start a warm engine (oil temperature must be at least 60°C).
Check the gap with a drill of the appropriate diameter -Y-. Set air damper gap see paragraph 4.47.
If the gap does not match, then adjust the screw -B- on the vacuum opening device.
Install the air filter.
