ALL-CARB 799868 Carburetor-Assy Replacement for 498170 498254 497314 6-6.75HP Engine Replacement for Murray Craftsman Snapper 22" Push Mower Carb

What It Is

The ALL-CARB 799868 Carburetor Assembly is a direct replacement for the OEM carburetor on 22-inch push mowers with 6-0 to 6.75-horsepower engines (typically Briggs & Stratton or Tecumseh). It’s designed for Murray, Craftsman, and Snapper models that use the 498170, 498254, or 497314 OEM carb numbers.

Fitment & Compatibility

• Engine types: Fits 6–6.75 HP engines with a horizontal shaft and standard bolt pattern. Most common on Briggs & Stratton single-cylinder engines from the 1990s–2010s.
• Deck size: Typically 22-inch push mower decks, but check your engine model number (stamped on the blower housing or engine shroud).
• OEM cross-reference: Replaces Craftsman/MTD part numbers 498170, 498254, 497314, and 799868. Some sellers also list it for 794304 and 791859.
• What to verify before buying: Confirm your mower’s engine model number (e.g., 12B902, 10T902, etc.) and that the carb has the same number of mounting holes (usually 2) and fuel inlet orientation (side or bottom). Measure the distance between mounting bolt centers (approx. 2.5 inches) to match.

Key Things to Know

• Quality check: This is an aftermarket carb, not OEM. It often works well out of the box but may need minor adjustment to the idle mixture screw. Some units require cleaning the jets with compressed air before install.
• Installation difficulty: Easy for anyone who’s replaced a carb before – remove old gasket, bolt on new carb, connect fuel line and throttle linkage. Expect 15–30 minutes.
• Common gotchas: The included gaskets may be thin or poorly cut – use a thin layer of gasket sealant or reuse the OEM gasket if it’s in good shape. The fuel line may be a tight fit; warm the line in hot water to soften it.
• Performance note: If your mower runs rich (black smoke, sooty plug), adjust the mixture screw (usually 1.5 turns out from lightly seated). If it runs lean (surging, hard to start), open the screw another half turn.

Should You Buy It

If you have a common 6–6.75 HP push mower with a failing original carb and want a cheap, quick fix that usually works without major tuning, this is a solid value. Skip it if you need exact OEM fit for a rare engine or if you’re not comfortable making minor adjustments to the idle mixture.
