Magnetic Pickup
(See Figure 3 or Figure 4)
The magnetic pickup provides an AC signal to the control
unit. Minimum voltage output from the pickup during
engine cranking should be 1.75 VAC.
Air Gap
(See Figure 3 or Figure 4)
The air gap between the ring gear and pickup should be
0.040 inches.
Measure the air gap at 3 or 4 places to get an accurate
reading.
To adjust air gap, loosen the locknut and turn pickup
clockwise until it just bottoms on the ring gear, then back
out 3/4 turns.
Hold pickup in this position while retightening locknut.
If loss of signal or failure of the pickup occurs while
running, the governor control will de-energize the
carburetor shut-off solenoid to stop the engine.
