Low Idle Mixture Screw Adjust Carburetor NOTE: Some engines may have a fixed (capped) idle fuel adjusting screw or limiter cap. On these engines, do not a empt steps 1 and 2 below. Proceed directly to Step 3.
The system requires an additional procedure for se ing the idle speed. If speed adjustments are required proceed as follows. Governed Idle Spring 1. Make any necessary speed or control adjustments following the appropriate instructions covered in this section. Tab 2. Move the thro le control to the idle position.
