Carburetor for Briggs & Stratton 594492 500cc 17.5hp Engine, Carb with Tune-Up Kit Replaces for Parts # 27761152

What It Is

This is an aftermarket carburetor assembly with a tune-up kit (spark plug, fuel filter, air filter) designed for Briggs & Stratton 500cc, 17.5hp single-cylinder engines. It replaces OEM part #27761152 and is typically used on riding mowers, lawn tractors, and zero-turn mowers.

Fitment & Compatibility

• Engine check: Confirm your engine model number (stamped on valve cover or blower housing). This carb fits Briggs & Stratton 500cc (17.5hp) engines with part #594492 specifically, and supersedes #27761152.
• OEM vs aftermarket: This is a non-OEM replacement. May need minor adjustment to idle mixture screw (if adjustable) and gasket alignment.
• Measurements: The carburetor flange bolt spacing is standard for this engine family. Measure your old carb’s mounting hole center-to-center distance (approx. 2.5 inches) to verify.
• Brand/deck size: Fits many MTD, Troy-Bilt, Craftsman, Husqvarna, and John Deere riders with the specified engine. Not tied to deck size—engine model is the only compatibility factor.

Key Things to Know

• Quality variance: At $19.99, this is a budget part. It often works well out of the box, but some units may have rough casting or require cleaning of debris from manufacturing.
• Installation difficulty: Moderate. You’ll need basic tools (socket set, screwdrivers, pliers). Plan 1–2 hours. The tune-up kit parts are generic—double-check spark plug gap (usually 0.030”) and fuel filter orientation.
• Common gotchas: The gaskets included may be slightly thicker than OEM—use a thin film of gasket sealer if you see fuel weepage. Also, the carb may be set too lean from factory; an adjustable idle screw lets you tweak it.
• Return policy: Since it’s a low-cost aftermarket part, test fitment before final assembly. Some sellers may not accept returns if installed.

Should You Buy It

If you have a Briggs & Stratton 500cc 17.5hp engine with a dead or clogged carb and want a budget fix with extra tune-up parts, this is a solid value. It’s best for DIYers who can handle minor adjustments and don’t mind aftermarket quality. Avoid if you need exact OEM fit or a drop-in solution with zero tweaking.
