3. Hold the governor lever away from the
carburetor so the thrott le lever is against the idle
speed (RPM) adjustment screw of the carburetor.
Start the engine and allow to warm up, then
adjust the screw to set approximately 1200 RPM.
Check using a tachometer. Turn the adjustment
screw (inner) clockwise (in) to increase or
counterclockwise (out) to decrease speed.
4. Release the governor lever and check that the
thrott le lever is in the idle (centered) position.
See Figure 5-9. Turn the governed idle (outer)
adjustment screw to obtain the equipment
manufacturer's recommended idle speed
(1500-1800 RPM). The governed idle speed
(RPM) is typically 300 RPM (approximate) higher
than the low idle speed. See Figure 5-10.
