MAINTENANCE

AIR CLEANER

All engines have an air cleaner cartridge. In addition, some engines have a pre-cleaner.

Pre-cleaner

To clean pre-cleaner (if equipped), separate it from cartridge and wash in liquid detergent and water. Squeeze dry in a clean cloth. Saturate in engine oil. Squeeze in clean, absorbent cloth to remove all EXCESS oil.

CAUTION: Do not use pressurized air or solvents to clean cartridge. Pressurized air can damage cartridge; solvents will dissolve cartridge.

SPARK PLUG

Use only Briggs & Stratton Spark Tester (part number 19368) to check for spark.

Note: To determine part number of replacement pre-cleaner and/or cartridge, measure height of part and find P/N below.

•Cartridge height = 2-1/2 in. . . . . . . . . . . . . . . . . 493910

•Pre-cleaner height = 2-1/2 in. . . . . . . . . . . . . . 272477

•Cartridge height = 3 in. . . . . . . . . . . . . . . . . . . . 496894

•Pre-cleaner height = 3 in. . . . . . . . . . . . . . . . . . 272403

•Cartridge and pre-cleaner height = 3 in. . . . . . . . . . 5053

Note: In some areas, local law requires using resistor spark plug to suppress ignition signals. If this engine was originally equipped with resistor spark plug, use same type for replacement.
