What It Is

This is a complete aftermarket carburetor kit for Briggs & Stratton engines, including the carburetor body plus a 795259 air filter, primer base, and gaskets. It’s designed for small engines on walk-behind mowers, pressure washers, and generators.

Fitment & Compatibility

Check your engine’s model, type, and code numbers (stamped on the blower housing or valve cover). This carburetor replaces OEM part numbers 498170, 799872, 694202, 497586, 498254, and 790821-14111. It fits many Briggs & Stratton single-cylinder engines from the 2000s onward, especially those with a plastic carburetor and primer bulb. Measure your carburetor mounting bolt spacing (typically 2.5" center-to-center) and the air filter stud length to confirm. Not compatible with side-draft or pulsa-prime systems.

Key Things to Know

• Quality variance: Aftermarket carburetors can have slightly different jetting than OEM. Expect occasional need to adjust the idle mixture screw or clean out machining debris.
• Installation difficulty: Moderate. Requires removing the old carburetor, swapping gaskets, and reconnecting fuel lines and governor linkage. A small screwdriver and pliers are typically enough.
• Primer bulb orientation: The included primer base must be seated firmly and oriented so the bulb clears the mower deck. Check for binding before tightening.
• Air filter fit: The 795259 filter is a common replacement but may not match all Briggs air cleaner housings exactly. Confirm the housing stud length and filter shape match your setup.

Should You Buy It

This is a solid budget option if you have a common Briggs & Stratton engine with a failed plastic carburetor (cracked body, stuck float, or bad primer bulb) and you’re comfortable with basic small-engine repair. It’s not for professional use or high-performance applications, but for a homeowner mower or backup generator, it’s a cost-effective fix that works for most users.
