Create a vacuum with a hand vacuum pump and adjust the valve with the adjusting bolt to a pressure of 35 kPa. To increase the vacuum, screw in the adjusting bolt; to decrease it, unscrew it.
Remove the 12mm thick plate.
Check whether a vacuum of at least 60 kPa appears in the maximum fuel portion position.
Install a 11.8 mm thick plate between the acceleration lever and the maximum speed adjustment bolt and check whether the vacuum is maintained at 60 kPa.
Replace the 11.8 mm plate with a 12.1 mm plate. In this case, there should be no possibility of creating a vacuum.
Disconnect the hand vacuum pump.
