This procedure applies to models before the year 1989 only. The adjustment of the Throttle Cable is important for transaxle performance because it sets the position of a valve within the transaxle that regulates the shift speed, shift quality, as well as part throttle downshift sensitivity. An adjustment that is too short may bring shifts forward and slip, on the other hand, an adjustment that is too long may also back the shifts off and erratic part throttle downshifts occur. Start the engine and let it warm up until normal operating temperature, cold start choke be off, carburetor throttle lever set at the normal curb idle position turn the engine off. Flip up the cable cover only to reveal the stopper and cover of the lower cable bracket and unscrew the bolt of the lower cable bracket. Loosen the tension of the lower cable, pull the stopper to get away from cover A to the above said distance, and then again make the tension till the cable bracket bolt comes to the prescribed torque, and measure the clearance. Last of all, adjust the throttle lever to adopt the wide open reset Position that the released end of the Throttle Cable must not bind.
