XT-7 Carburetor 14 853 49-S for Husqvarna 6021P HU600F, for Kohler Courage XT675 XT650 XT6.5 XT6.75 149cc 173cc Engine Lawn Mower with 14-743-03-S Air Filter Cover Kit

What It Is

This is a complete aftermarket carburetor assembly (Part #XT-7, OEM cross 14 853 49-S) for Kohler Courage XT-series engines (149cc–173cc) found in Husqvarna 6021P and HU600F walk-behind mowers. It replaces the factory carb when yours is clogged, leaking, or failing.

Fitment & Compatibility

Check engine model, not just mower brand. This fits Kohler Courage XT675, XT650, XT6.5, XT6.75 (vertical shaft). Verify your engine’s model/spec number is on the list—usually stamped on the engine shroud or valve cover. It will not fit older Kohler Command or Kawasaki engines.

Also includes 14-743-03-S air filter cover kit, but confirm your existing filter matches. Measure mounting stud spacing on your current carb (this uses standard 2-bolt intake flange). Not for side-draft or horizontal shaft engines. Deck size is irrelevant—only engine matters.

Key Things to Know

• Aftermarket part, not OEM Husqvarna/Kohler. Quality is generally good for the price, but some users report needing to adjust idle mixture screw (usually 1.5–2 turns out from lightly seated).
• Installation is moderate. You’ll need a 10mm socket, screwdriver, and possibly a new gasket (check if included). Fuel line connections are push-fit; replace old clamps if brittle.
• Common gotcha: The included air filter cover may not seal perfectly on all variants—test fit before reassembling. Also, drain old fuel and clean the tank to avoid re-clogging.
• Not a universal fit—double-check intake manifold shape. If your engine has a different choke linkage (e.g., remote cable vs. lever), this may not connect properly.

Should You Buy It

Buy this if you have a Kohler Courage XT-series engine (149–173cc) and your original carb is beyond cleaning—it’s a cost-effective fix for surging, hard starting, or flooding. Skip it if you need exact OEM fitment or have a non-Courage engine. For the price, it’s a solid DIY solution for a common mower problem.
