What It Is

This is a replacement carburetor for Toro 22-inch Recycler lawn mowers powered by Kohler XT-series engines (XT675, XT650, XT6.5, XT6.75). It mixes fuel and air for combustion and is a direct drop-in replacement for the OEM carburetor when yours is clogged, warped, or leaking.

Fitment & Compatibility

Check these before buying:

• Engine model: Must be Kohler XT675, XT650, XT6.5, or XT6.75 (149cc). Look for the engine model stamped on the valve cover or blower housing.
• Mower models: Fits Toro 20378, 20371, 20377, 20171 – all 22-inch Recycler decks. Not compatible with other Toro models or non-Kohler engines.
• OEM vs aftermarket: This is an aftermarket part. It matches the OEM carburetor dimensions and mounting pattern but may not have the exact same jetting or gasket quality.
• Physical check: Ensure the mounting flange bolt pattern (two bolts, 2.5 inches center-to-center) matches your current carb. The fuel inlet and primer bulb orientation should align with your fuel line and air filter housing.

Key Things to Know

• Quality: Most users report it works out of the box, but a few note the gaskets are thin or the primer bulb feels less durable than OEM. Consider reusing your original gaskets if they’re in good shape.
• Installation difficulty: Easy – typically 20-30 minutes. Remove the air filter housing, disconnect the fuel line and throttle linkage, unbolt the old carb, and reverse. No special tools needed beyond a socket set and pliers.
• Common gotchas: The fuel line may be stiff from age – warm it with a heat gun or soak in hot water to avoid cracking. After install, prime the bulb until fuel flows, then start. If the engine hunts or stalls, check for air leaks at the intake gasket.
• Tuning: This carb is non-adjustable (fixed jets). If your mower runs rich or lean, you may need to clean the OEM carb instead or adjust the idle screw (if present) on the throttle plate.

Should You Buy It

Buy this if your Toro 22-inch Recycler with a Kohler XT engine won’t start or runs poorly due to a gummed-up or damaged carburetor, and you want a cheap, quick fix without rebuilding the original. It’s a solid budget option for DIY homeowners, but if you need exact OEM performance or have a high-hour engine, consider the genuine Toro/Kohler carburetor instead.
