Adjust the speed of the calibration bench to the specified "LOAD STOP ADJ" rpm. Adjust the screw for the load stop adjustment (4) to the output dimension for the "LOAD STOP ADJ".Tighten the locknut for the screw for the load stop adjustment (4) and check the dimension again.
Increase the speed of the calibration bench by a minimum of 100 rpm. Then reduce the speed back to the original "LOAD STOP ADJ" rpm in order to check the governor output dimension again.If the "LOAD STOP ADJ" dimension is not within the specified "RECHECK TOL", perform Step 4 again.
Adjust the speed of the calibration bench to the specified "FUNC CHECK #1" rpm. The "MAX OUTPUT" dimension must be 0.0 mm (0.00 inch).
Adjust the speed of the calibration bench to the specified "THROT STOP ADJ" rpm. Adjust throttle stop adjustment screw (2) in order to obtain the output dimension for the "THROT STOP ADJ" that is specified in the TMI. Tighten the locknut for throttle stop adjustment screw (2). Check the output dimension again.
Increase the speed of the calibration bench by a minimum of 100 rpm. Then reduce the speed of the calibration bench back to the original "THROT STOP ADJ" rpm. Check the output dimension for the "THROT STOP ADJ"again.If the dimension is not within specifications, perform Step 7 again.
Adjust the speed of the calibration bench to the "FUNC CHECK #2" rpm that is specified in the TMI. The output dimension of the "FUNC CHECK #2" should be within the specifications in the TMI. If the output dimension is not within the specifications, repeat steps 4 through 9.
Adjust the speed of the calibration bench to the specified "FUNC CHECK #3" rpm. The output dimension of the "FUNC CHECK #3" should be within the specifications in the TMI. If the output dimension is not within the specifications, inspect the torque cam for the correct part number or excessive wear. If the torque cam needs to be replaced, refer to the Disassembly and Assembly, "Governor (Type) - Disassemble" and Disassembly and Assembly, "Governor (Type) - Assemble" sections in this manual.Note: If the governor is not equipped with a fuel ratio control proceed to Step 14. If the governor is equipped with a fuel ratio control, continue with Step 11.

If the governor is equipped with a fuel ratio control, purge the air pressure to the fuel ratio control. Adjust the speed of the calibration bench to the "FRC ADJ" rpm that is specified in the TMI. Adjust the screw for the fuel ratio control (C) in order to obtain the "FRC ADJ" dimension that is specified in the TMI. Tighten the locknut.
Apply air pressure to the FRC for approximately three seconds. Purge the air pressure to the FRC. Rotate the throttle lever from the
