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.
