796031 Tune Up Kit, Air Filter, Oil Filter, Spark Plug, Fuel Filter, | Compatible with Briggs & Stratton 591334 492932 696854, John Deere D100-D140, Husqvarna YTH Series Lawn Mower

What It Is

This 796031 tune-up kit bundles the four essential service items for a single-cylinder Briggs & Stratton engine: air filter, oil filter, spark plug, and fuel filter. It’s designed for riders and zero-turns using Briggs & Stratton 500–700 series engines, commonly found on John Deere D100–D140 and Husqvarna YTH models.

Fitment & Compatibility

Before buying, confirm your engine model number (stamped on the valve cover or blower housing). This kit replaces OEM Briggs & Stratton numbers 591334 (air filter), 492932 (oil filter), 696854 (spark plug), and the included fuel filter is a generic in-line type. It fits most 500, 600, and 700 series single-cylinder engines, plus many 10–20 hp horizontal-shaft engines. Not compatible with V-twin engines or engines with remote oil filters. Measure your existing oil filter thread (typically 3/4-16) and fuel line diameter (commonly 1/4" or 5/16") to ensure the fuel filter fits your hose.

Key Things to Know

• Quality: Parts are aftermarket but meet or exceed OEM specs. The spark plug is a standard J19LM or equivalent; gap it to 0.030" before installation.
• Installation difficulty: Easy—basic hand tools (socket set, spark plug wrench, pliers) and about 20 minutes. No special skills needed.
• Common gotcha: The fuel filter may be too small or large for your fuel line; check your line ID and buy a separate filter if needed. Also, the air filter is foam or paper depending on your engine—verify your engine’s air box design.
• What’s not included: No gaskets, seals, or instructions. You’ll need to reuse or replace the oil drain plug gasket separately.

Should You Buy It

If you own a single-cylinder Briggs & Stratton engine on a rider or zero-turn and want a simple, cost-effective way to perform annual maintenance, this kit is a solid value at $16.99. It’s not for V-twins or engines requiring specialized filters, but for the common 500–700 series, it covers everything you need in one box.
