What It Is

This is a complete carburetor assembly for Briggs & Stratton 625, 650, and 6.5 HP single-cylinder engines, commonly found on walk-behind mowers, pressure washers, and small generators. It replaces the original carburetor and includes the 491588s air filter, making it a drop-in fix for fuel-related starting issues.

Fitment & Compatibility

• Engines: Fits Briggs & Stratton models 625 (Series 6150N, 6150), 650 (Series 6150), and 6.5 HP (Series 6150). Also compatible with older 6 HP BS engines.
• OEM replacements: Replaces 497314, 14111, 497586, 498254, 498966, 498255, 799868, 498170.
• Air filter: Includes the 491588s filter (fits many Briggs 600–700 series engines).
• What to check: Confirm your engine’s model number (stamped on the blower housing, e.g., “6150N”). Measure the mounting bolt spacing (typically 2.5 inches center-to-center). Ensure your fuel line diameter matches (3/16 inch common). This carb does NOT fit OHV or Intek engines—only L-head (side-valve) models.

Key Things to Know

• Quality vs. OEM: It’s an aftermarket carb, not genuine Briggs. Most users report it works fine, but some note the gaskets may be thinner than OEM—check for air leaks after install.
• Installation difficulty: Easy for DIYers—remove the old carb, clean the mounting surface, install with included gaskets, and adjust idle mixture screw (initial setting: 1.5 turns out). No special tools needed.
• Common gotchas: The fuel bowl may have a small burr on the inlet—file it smooth if fuel leaks. Use fresh gas and a new fuel filter to prevent debris from clogging the tiny jets. If the engine runs lean, check the air filter fitment; the included one may be slightly loose.
• Adjustment tip: If the mower surges, turn the idle mixture screw in (clockwise) 1/4 turn at a time until it stabilizes.

Should You Buy It

Buy this if your Briggs 625/650/6.5 HP engine won’t start or runs poorly due to a clogged carb, and you want a cheap, complete fix without rebuilding the old one. It’s a solid budget option for DIY homeowners—just double-check your engine model and mounting pattern first. Skip it if you need an exact OEM part for a commercial mower or a warranty repair.
