PROCEDURE

Strobe-Tach Method

1.Turn the engine off.

2.Place a highly visible mark on a component that rotates while the engine is running. The rotor- cooling fan is a good place for this mark. See Figure F.1.

3.Connect the strobe-tach according to the man- ufacturer’s instructions.

4.Start the engine and place the idle switch in the “HIGH IDLE” position. Make sure that there is no load on the machine.

5.Direct the strobe-tach light at the mark and syn- chronize the strobe-tach.

6.The tach should read between 3700 and 3800 RPM.

7.Move the idle switch to the “AUTO IDLE” posi- tion and wait for the idle solenoid to energize. The engine RPM should drop and stabilize at the low idle RPM.

8.Synchronize the strobe-tach to read the low idle RPM.

9.The tach should read between 2250 and 2500 RPM.

10.If either of the readings is incorrect, proceed to the Throttle Adjustment Procedure in this section.
