(d) Rotate the engine as required to locate a ring gear tooth directly below the tapped, pickup
mounting hole. An imaginary line should pass through the center of the mounting hole, the center
of a flywheel tooth and the center of the flywheel.
(e) Install the magnetic pickup into the tapped mounting hole and thread it in until the tip touches
the "in-line" flywheel gear tooth.
CAUTION: THE PICKUP TIP MUST BE DIRECTLY OVER A TOOTH AND NOT BETWEEN TEETH
WHEN ADJUSTMENT IS MADE.
(f) Back the pickup outward (counterclockwise) 1/2 turn. Hold the pickup securely in this position
and tighten nut (3). This adjustment will result in a clearance of approximately 0.028 inch between
the pickup tip and the flywheel teeth and give an operating AC voltage of 4 V to 8 V at controller
terminals 5 and 6 when the engine is running at no load and governed speed, and approximately
2.5-V at cranking speed.
NOTE: As little a 1-V is required for operation of governor control box. Magnetic pickup voltage does not
have to be 4-V to 8-V.
