FUEL SYSTEMTM 5-3805-263-14&P-21. Turn dashpot adjustment screw (1) in (clock-wise) until it stops.2. Turn dashpot adjustment screw out (counter-clockwise) 1/2 ± 1/4 turn.Checking Balance PointThe balance point for the engine is:1. At 20 rpm higher than full load speed.2. The point where the power adjustment screw isagainst the load stop.3. The point where the engine has the most horse-power output.4. The point where an increase in load on the engineputs the engine in a lug condition (a condition inwhich a small increase in load makes the enginespeed get much less).Procedure for Checking Balance PointNOTE: It is important,to the correct operation ofthe transmission, that the BALANCE POINT isadjusted to the correct specifications.NOTE: The rack setting must be correct beforean adjustment is made to the balance point.I. Connect a tachometer which has good accuracyto the tachometer drive.TESTING AND ADJUSTING2. Connect a continuity light to the brass terminalscrew (1) on the rear of the governor. Connectthe other end of the light to a place on the fuelsystem which is a good electrical ground.3.4.5.6.7.8.9.10.11.Start the engine.With the engine at operating conditions, run theengine at high idle.Make a record of the speed of the engine at highidle.Add load on the engine slowly until the contin-uity light just comes on. This is the balancepoint.Make a record of the speed at the balance point.Repeat Step 6 several times to make sure thatthe recording is correct.Stop engine. Make a comparison of the recordsfrom Steps 5 and 7 with the information givenin the FUEL SETTING INFORMATION.If the full load speed is not correct, adjust theHIGH IDLE speed to make a change in the fullload speed.If the high idle speed is out of tolerance and thefull load speed is correct, look for a weak gover-nor spring or the wrong governor spring. Boththe full load speed and the high idle speed mustbe in the tolerance given in the FUEL SET-TING INFORMATION.1-56
