XT675 Carburetor for Kohler XT650 XT675 6.5hp 6.75hp 149cc Engine 14 853 68-S Carburetor for Toro 22 Recycler 20371 20378 20377 20370 Lawn Mower Tune Up Kit

What It Is

This is a complete carburetor and tune-up kit designed for Kohler XT650 and XT675 6.5–6.75hp 149cc engines, commonly used in Toro 22-inch Recycler lawn mowers (models 20371, 20378, 20377, 20370). It replaces the OEM part 14 853 68-S and includes the carburetor, gaskets, fuel filter, and spark plug for a full service.

Fitment & Compatibility

Before buying, confirm your engine is a Kohler XT650 or XT675 (check the engine shroud or model tag). This kit fits Toro 22-inch Recycler models 20371, 20378, 20377, and 20370—verify your mower’s model number under the seat or on the frame. It is an aftermarket replacement, not OEM Kohler, so check that the mounting holes, fuel inlet, and throttle linkage match your existing carburetor. Measure the carburetor base gasket pattern (typically 2-bolt) and ensure the bowl diameter is the same (about 2 inches). Not compatible with other Kohler engine series (e.g., Courage, Command) or non-Toro mowers.

Key Things to Know

• Quality is good for the price – Users report it runs well out of the box, but some need minor idle or mixture screw adjustment. Expect it to last 1–2 seasons with clean fuel.
• Installation is moderate – You’ll need basic tools (screwdriver, socket set) and about 30 minutes. Watch for small springs and linkage alignment when swapping.
• Common gotcha: fuel line routing – The fuel inlet is on the same side as the old carb, but the line may need trimming or a new clamp to avoid kinks.
• Tune-up kit completeness – Includes a spark plug (check gap before installing) and fuel filter, but not air filter or oil. Replace the air filter separately for best results.

Should You Buy It

If you own a Toro 22-inch Recycler with a Kohler XT650 or XT675 engine and need a quick, affordable fix for hard starting, surging, or fuel leaks, this kit is a solid choice. It’s not OEM, but the high rating and low price make it a practical replacement for most DIY owners. Avoid it if you want a perfect factory match or have a different engine model.
