The system requires an additional procedure for seing

the idle speed. If speed adjustments are required

proceed as follows.

1. Make any necessary speed or control adjustments

following the appropriate instructions covered in

this section.

2. Move the throle control to the idle position. Hold

the governor lever away from the carburetor, or

hold the throle lever so it is tight against the idle

speed adjusting screw, to negate the governor

activation. See Figure 19. Check the speed with a

tachometer and adjust it to 1500 RPM.

3. Release the governor lever and allow the engine to

return to the governed idle speed. Check it with a

tachometer against the equipment manufacturers

recommended idle speed. Governed Idle Speed

(RPM) is typically 300 RPM (approximate)

higher than the low idle speed. If adjustment is

necessary, bend the adjusting tab on the speed

control assembly to set. See Figure 18.
