0000001901 W-CSD ADJUSTMENT

Adjustment of the W-CSD 1. Timer advance adjustment (refer to Fig 1 [O], 3 [Q]). (1)Determine the timer advance angle from the graph in Fig. 3 (Q). (2)(1) Adjust with the screw (A) so that the timer advance angle determined in the item (1) is obtained. 2. Setting the intermediate lever position (refer to fig 1 and fig 2) (1)Insert a block gauge L1 between the idle set screw (G) and the lever (H). (2)When the intermediate lever (D) is perpendicular, fix it so that it contacts the control lever (F). (3)Align lever (D) perpendicular to the aligning mark (J). 3. W-CSD lever adjustment [refer to fig 1 (O) and fig 2 (P)] (1)Insert a block gauge L2 determined from the graph (L-t) in the figure 3 (Q) between the idling set screw (G) and the lever (H). (2)Adjust screw (B) so that the W-CSD lever (C)'s roller contacts the intermediate lever (D) and fix using the nut. The temperature of the wax at adjustment must not exceed a. Note: When inserting the block gauge, separate lever (C) and (D) using screw (B) to prevent excessive force on the lever.
