Adjustment
NOTE
Do not turn the adjusting ring more than 1/16 inch
(1.5875 mm) during any one adjustment.
If the advance varies more than 2° at 300 rpm when the
oil pressure drain button is depressed, the advance
should be retarded slightly. This variance indicates the
mechanical retard stop is not in phase with the hydraulic
valve.
1. If advance assembly fails to pass the test, it may be adjusted by rotating the adjusting ring (16).
2. Note whether advance assembly advances too soon or too late. Either condition can normally be corrected by
rotating the adjusting ring (16).
