What It Is

This is a pre-assembled tune-up kit for Craftsman riding mowers with 42" or 46" decks, containing an air filter, oil filter, and spark plug. It’s designed for routine maintenance on models using 19.5hp, 20hp, or 21hp Briggs & Stratton engines.

Fitment & Compatibility

Before buying, verify your specific mower model number (found under the seat or on the frame tag). This kit explicitly fits Craftsman 917.250810, 917.280330, 917.287210, 917.287240, 917.288100, and 917.288516. It’s an aftermarket set, not OEM Briggs & Stratton. The air filter is a foam or paper type—check your current filter shape (this kit uses a rectangular, pre-oiled foam filter for most B&S Intek engines). The oil filter is a standard spin-on type (cross-reference with OEM Briggs 492932 or equivalent). The spark plug is a standard J19LM or equivalent (gapped to 0.030"). Do not assume it fits all Craftsman or all B&S engines—double-check your engine model and deck size.

Key Things to Know

• Quality concerns: At $22.98 with a 3.7 rating (only 5 reviews), expect basic aftermarket parts that may not match OEM fit or longevity. Some users report air filter foam being thinner or oil filter threads not seating perfectly.
• Installation difficulty: Easy—20 minutes with basic hand tools. No special skills needed, but you’ll need a spark plug socket (5/8" or 13/16") and an oil filter wrench.
• Common gotchas: The spark plug may come pre-gapped—always verify and adjust to 0.030". The air filter may require a light coating of engine oil before installation (check instructions). The oil filter cross-threads easily—hand-tighten only.
• No OEM guarantee: This is not a genuine Briggs & Stratton kit. If you have a newer engine with different filter dimensions (e.g., longer oil filter), this kit won’t work.

Should You Buy It

Buy this kit if you need a quick, cheap tune-up for a listed Craftsman model and don’t mind aftermarket quality. It’s fine for basic maintenance, but if you want guaranteed fit and longer life, spend a few dollars more for OEM Briggs & Stratton parts. Skip it if you have a non-listed model or a newer engine with different filter specs.
