Air Cleaner
1. Remove the wing nut, cover and element.2. Clean the inside of the cover. The base should be clean. If the base is dusty, the air cleaner gasket leaked; discard the element.3. Inspect the new element for damage and dirt.
REMOVING THE ELEMENT4. Install the new element and cover.The element removed may be cleaned or discarded, depending upon the apparent condition of the pleats. If a cleaned element is installed, and the exhaust smoke and/or loss of power continues, remove and discard that element and install a new element. Install a new element at least once a year.Cleaning With Pressure Air
1. Use clean, dry air - 30 PSI maximum. Hold the nozzle at least one inch from the element and at a slight angle. (A direct blast can rip the pleating.)2. Direct the air stream along the complete length of each pleat on the CLEANEST side of the element. (This will loosen the dirt from the dirtier side.)3. Blow the loosened dirt from the DIRTY side.4. Direct the air from the CLEAN side through to the DIRTY side to remove any dirt blown into the pleats.
CLEANING THE ELEMENT WITH PRESSURE AIRCleaning With Water
1. Use clean water - 40 PSI maximum. Do not use a nozzle.2. Direct the water stream along the complete length of each pleat on the CLEAN side of the element.3. Direct water along the complete length of each pleat on the DIRTY side of the element.4. Rinse the CLEAN side of the element.5. Allow the cleaned element to dry thoroughly.Cleaning With Detergent
1. Wash both sides of the element in a solution of warm water and non-sudsing household detergent.2. Rinse the CLEANEST side of the element with clean water (40 PSI maximum) along the complete length of each pleat.3. Rinse the opposite side of the element along the complete length of each pleat.4. Rinse the first side again to remove all loosened dirt.5. Allow the cleaned element to dry thoroughly.Checking Cleaned Element
Hold the dried element in front of a lighted electric bulb. Carefully inspect the element for tiny, pin-points of light. Any light showing indicates a pleat has ruptured and will tear with further use. Discard the element.1. Wrap usable elements in heavy paper.2. Store the wrapped element in a dry, clean place.Valve Lash
Preparing To Check Adjustment
TDC of the No. 1 piston on the compression stroke is the reference point. The No. 1 piston is at TDC compression stroke when the timing mark on the damper or the pulley is aligned with the timing pointer, and No. 1 and No. 2 exhaust and inlet valves are closed. (The rocker arms are free and the push rod is at its lowest point.)
NUMBERING OF CYLINDERS AND VALVE LOCATIONTo Check Valve Lash
1. Stop the engine.2. Clean around the valve covers.3. Remove the crankcase ventilation valve.4. Remove both valve covers.
REMOVING CRANKCASE VENTILATION VALVE5. Turn the crankshaft until No. 1 cylinder is on top dead center ("TC1") compression stroke. Align the ("TC1") timing mark on the damper with the timing pointer
