Figure 57.  Adjusting Governor Using Tool SE-2072-2
Figure 55.  Accelerating Pump Lever Adjustment 1.  Location of Pump Cam 2.  Clearance Between Pump Lever and Adjusting Screw With Throttle Wide Open Accelerating Pump Stroke Adjustments To  satisfy  acceleration  requirements  in  various  climates,  the accelerating pump discharge can be adjusted (Fig.  55). The  bottom  hole  (No.    2)  in  the  acceleration  pump  cam  and the  throttle  lever  provides  the  maximum  pump  discharge  for extreme  cold  weather  and  the  top  hole  (No.    1)  provides  the minimum  pump  discharge  for  warm  weather  operation.    If  a change in the adjustment is required, make certain the proper hole (top or bottom) in plastic accelerating pump cam, located behind the throttle lever, is properly aligned (indexed) with the numbered   hole   (top   or   bottom)   in   the   throttle   lever   before installing the retaining screw. Dashpot With engine temperature normalized and engine operating at specified    curb    idle    speed,    depress    dashpot    plunger    and measure   distance   between   plunger   and   throttle   lever   (see SPECIFICATIONS).  The shank of a new drill may be used to check this adjustment. To adjust the setting, loosen locknut and screw the dashpot in or  out  as  required.    When  the  desired  setting  is  obtained, tighten locknut on dashpot against the bracket.  Recheck idle speed. Throttle Modulator With vacuum applied to throttle modulator loosen locknut and adjust modulator until engine operates at specified RPM (see SPECIFICATIONS). Governor Adjustment (Spinner Type) The   procedure   outlined   below   should   be   followed when making a governor spinner adjustment.  It is necessary to use a tachometer to adjust engine RPM. Adjust the governor spinner so that engine speed will cut     off     within     the     engine     no     load     cutoff     range     (see SPECIFICATIONS). 1.   Turn off ignition.  Engine must be completely stopped. 2.   Remove governor clamp and gasket assembly. 3.   Turn engine over until adjusting screw whole plug appears in the opening. 4.   Remove plug with 1/8” Allen Wrench (Fig.  56).   Figure 56 Using Allen Wrench to Remove Governor Plug Fig.  56.  Using Allen Wrench to Remove Governor Plug 1.  Distributor  2.  Allen Wrench 3.  Governor Plug 5.   Insert slotted end of SE-2072-2 governor adjusting tool firmly in hole, engaging adjusting tang (Fig.  57).  Turn the handle clockwise to decrease speed and    counterclockwise to increase speed; ¼  turn will change the speed approximately 100 RPM. 6.   The adjusting screw is of a special design.   The spinner cannot be adjusted with a   screwdriver or by any device other than this tool. 7.   Reinstall plug with 1/8” Allen Wrench before checking governor speed.
