What It Is

This is a complete replacement carburetor with an air filter for Briggs & Stratton 12.5HP single-cylinder engines, commonly used on Craftsman and Murray lawn tractors from the early 2000s. It replaces multiple OEM part numbers and restores fuel delivery and air filtration in one kit.

Fitment & Compatibility

Before buying, verify your engine model number (not just mower model). This carb fits Briggs & Stratton 12.5HP engines with model numbers 5-4993, 498027, 498231, 499161, 494502, 494392, 495706, and 498134. Also check your mower’s deck size—typically 38–46 inches for these tractors—but the carb is engine-specific, not deck-specific. Confirm your existing carburetor mounting pattern and fuel line diameter (usually 1/4 inch). This is an aftermarket part, not OEM; if you need exact factory fit, stick with Briggs & Stratton.

Key Things to Know

• Quality is decent for the price but not premium. Some users report needing to adjust the idle mixture screw or clean out machining debris before installation.
• Installation is straightforward if you’re comfortable with basic tools (screwdriver, pliers). Expect 30–60 minutes including the filter swap.
• Common gotcha: The gaskets may be slightly thicker than OEM—ensure the carb seats flush to avoid air leaks. Also, the included filter may not match all housing shapes; compare it to your old one before installing.
• Fuel line and primer bulb are not included. Reuse your old ones or buy separately if cracked.

Should You Buy It

This is a solid budget fix if your current carb is clogged or leaking and you’re comfortable with minor adjustments. It’s not for professionals needing long-term reliability, but for a weekend repair on a 10+ year old mower, it’s hard to beat the value. If you want zero fuss, spend more on an OEM part.
