0000001901 W-CSD ADJUSTMENT

Adjustment of the W-CSD
1. Adjustment of the advance angle of the timer
(1)Determine the timer advance angle using the graph.
(2)Adjust screw A so that the timer advance angle determined in item (1) is obtained.
2. Adjustment of the W-FICD
(1)Insert a block gauge thickness L between the control lever (D)'s adjusting screw (F) and the idle stopper (E).
(2)Adjust using screw B so that the control lever contacts the FICD lever pin and fix using the nut.
