Throttle and air mixture adjustment screws are factory sealed. The circulating mixture adjustment screw is not sealed, since its rotation does not have a significant effect on the CO content. Throttle adjustment, as a rule, does not require.
Adjustment of the combustible mixture is required only when the CO content in the exhaust gases is above the norm. When carrying out this adjustment, it is necessary that the valve clearance hydraulic compensators, the breaker contact closing angle, the ignition timing and the gap in the candles are normal.
