What It Is

This is a complete carburetor assembly for Briggs & Stratton single-cylinder engines, typically found on walk-behind lawn mowers, pressure washers, and small utility engines in the 5 HP range. It replaces multiple OEM carb numbers (495426, 495951, 492611, 490533, 692784) and includes a 491588S air filter.

Fitment & Compatibility

Before buying, confirm your engine’s model number (stamped on the blower housing or valve cover). This carb fits Briggs engines with these specific carburetor part numbers: 495426, 495951, 492611, 490533, 692784. It also works with engine series 135202, 130202, 137202, 135212, 133202, 134202, 133212, 112202, 112231, 112232.

Measure your old carb’s mounting flange bolt spacing (center-to-center) – it should be roughly 2.5 inches. This is an aftermarket part, not OEM, so the gasket may need trimming or the float height may need adjustment. Check that your mower deck or application uses a 5 HP Briggs engine – larger engines (6.75 HP+) use a different carb.

Key Things to Know

• Quality varies: Many users report it works out of the box, but some get a sticky float or gasket that leaks. Inspect the float bowl gasket and needle valve before install.
• Installation difficulty: Moderate. You’ll need a socket set, screwdriver, and possibly a small wire brush to clean the intake port. Expect 20–40 minutes.
• Common gotcha: The supplied air filter may not fit all air box housings. Compare the filter’s outer diameter and thickness to your original.
• Tuning: After installing, you may need to adjust the idle mixture screw (if present) and check for fuel leaks at the bowl and gasket.

Should You Buy It

Buy this if you have a confirmed compatible Briggs 5 HP engine and want a low-cost replacement that includes a new air filter. Skip it if you need an exact OEM fit for a commercial mower or if your engine is larger than 5 HP – then spend more on a genuine Briggs carb. For most homeowners, this is a solid budget fix.
