MAINTENANCE AND LUBRICATION Adjustments Oil Pump - 250 Engines 1. Before adjusting the oil pump, check the engine idle RPM and carburetor settings in the owner's manual supplement. 2. Loosen throttle cable jam nut and turn the adjuster (1) in or out until there is 1/16″ - 1/8″ (.16 - .32 cm) of throttle lever travel before the throttle slide starts to open. See your owner's manual supplement. 3. Place very slight pressure on the throttle lever (2) until all freeplay is removed from the throttle cable (to the point where the carb slide is just starting to rise). 4. Loosen the locknut (3). Turn the adjuster in or out until all freeplay is removed from the oil pump cable (the point where the oil pump arm is just starting to move off its stop). The pump stop keeps the pump arm from rotating any further down than the idle position so no visual alignment of marks is necessary. Tighten the locknut. 1 3 2 3 102
