Governor Adjustment (Before starting engine)

IMPORTANT: If carburetor has been removed or governor linkage disassembled, the governor lever, throttle restrictor and secondary governor spring must be adjusted before the engine is started.

Governor Lever Adjustment (Fig. 2)

All linkage must be installed to make adjustment. Loosen governor lever bolt and nut. Push on governor lever until throttle is wide open. DO NOT bend governor link. Hold lever in this position and rotate governor shaft counterclockwise as far as it will go. Hold lever and shaft in position and torque governor lever bolt and nut to 70 in-lb.

Throttle Restrictor Adjustment (Fig. 3)

Move throttle control lever to SLOW position. Hold governor lever so that throttle lever touches idle speed adjustment screw. Use tang bender (Briggs & Stratton Tool #19352) and bend throttle restrictor tang so throttle opening is limited to 1/4 in. travel when governor lever is released.

Secondary Spring Adjustments (Fig. 4)

With throttle control lever in SLOW position, install adjustment gauge (Brigss & Stratton Tool #19385) over end of governor lever as shown. Holding gauge in position, bend tab so that all slack is removed from secondary governor spring between its two anchor points. DO NOT STRETCH SPRING. Remove adjust- ment gauge.
