Z134 Governor adjustment

Warm up the engine and adjust carburetor mixture. Disconnect governor rod at carburetor and adjust engine idle speed stop screw to obtain 400-450 rpm. Reconnect governor to carburetor rod.
Start engine and open the hand throttle to wide open position. Desired engine speed of 2175-2225 rpm can be obtained by loosening the U bolt and rotating same on throttle rod until correct engine speed is reached. Retighten U bolt. With engine operating at 1000 rpm check for surging or unsteady running. If surging exists, check for and remove any binding in the operating linkage. If surging still exists, turn the bumper screw in until surging is eliminated and lock the adjustment.
If major adjustment is required follow this. With the throttle rod and the throttle butterfly valve in the wide open position, adjust rod to provide 1/32" over travel. Disconnect lever arm rod at upper end and remove.
Set hand throttle control lever to the idle position and observe if governor compensating spring link is contacting the throttle rod. If governor compensating spring link is not contacting the throttle rod, loosen the U bolt and rotate link until it just touches the throttle rod. Retighten U bolt.
Reinstall lever arm rod and with the hand control in the idle position, remove governor lever spring. Adjust length of rod by loosening the lock nut and rotating the rod in the plunger until the bottom of the plunger just contacts the governor lever. Reconnect the spring and retighten the locknut. Make the minor adjustments as above.

I hope this helps instead of adding confusion. If the governor does not work at all, you'll have to disassenble it and find out what's wrong.

Good luck,
