4.Squeeze wheel drive control lever (X, Figure 5-1) against handlebar. Measure between the coiled ends of the stretched spring (W, Figure 5-4), making sure you measure between the same coils used in step 3. The spring length should now measure 1/2" (13mm) longer than the measurement taken in step 3. If it does not, loosen jam nut (Y, Figure 5-4) and turn ad- juster (Z, Figure 5-4) to increase or decrease the spring length. (1-1/4 turns of the adjuster equals 1/16" [1.5mm] of spring extension.) Hold the adjuster and tighten the jam nut

(Y) when the correct spring length is obtained. Re-check measurements and adjust if needed.

If after completing this adjustment the wheels do not drive adequately, refer to Drive Disc Clearance Adjustment in this Section. Then repeat this adjustment.
