NOTE: This tachometer has an air core meter. The tach pointer
may not always rest at zero. This is normal. When engine
is started, pointer will position on the correct RPM.
To change the calibration of the tachometer, remove the flat head screw at the rear of the cup.
Carefully slide the cup back along the wires to expose the inner case. Remove the snap in light
socket assembly to access the cylinder select switches. The switches are located to the left of
the light hole. Use a small screwdriver or an unwound paper clip to change the switch settings.
