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.
