HU675AWD Carburetor For Husqvarna HU675 AWD LC121FH LC 121 FH 96145001501 Toro 20377 22in Lawn Mower with Kohler 6.75 Engine

What It Is

This is an aftermarket carburetor assembly for Husqvarna HU675 AWD and Toro 20377 22-inch walk-behind mowers equipped with the Kohler 6.75 ft-lb engine. It replaces the factory carburetor to fix starting issues, surging, or poor fuel delivery.

Fitment & Compatibility

Check these before buying:

• Engine type: Kohler 6.75 ft-lb (not 6.75 hp or other Kohler models). Verify your mower’s engine model number on the valve cover or blower housing.
• Mower model: Husqvarna HU675 AWD, LC121FH, LC 121 FH (96045001501, 96145001501) and Toro 20377, 20378. Not for non-AWD Husqvarna or other Toro series.
• Deck size: 22-inch walk-behind only.
• OEM vs aftermarket: This is a non-OEM part. It may lack the exact factory needle/seat tolerances. Expect minor fitment differences (e.g., gasket thickness, screw length).
• Physical check: Measure your old carburetor’s mounting bolt spacing (center-to-center) – should be about 2.25 inches. Confirm the fuel inlet and choke linkage positions match.

Key Things to Know

• Quality: Typical for the price. Some units arrive with dirt or debris in the bowl – flush with clean gasoline before installing.
• Installation difficulty: Moderate. You’ll need to swap the throttle/governor linkage and possibly reuse your old bowl gasket if the included one is too thick. Expect to adjust the idle mixture screw (usually 1.5 turns out from seated).
• Common gotchas: The choke plate may be slightly misaligned – bend it gently with pliers if it doesn’t seat fully. The fuel line may need a small clamp (not included). Surge issues after install often mean the new carb needs cleaning or the old gasket is leaking.
• Return policy: Since it’s under $20, returns may not cover shipping. Consider buying two if you need a spare.

Should You Buy It

If your Kohler 6.75 mower won’t start or runs rough and you’re comfortable with basic carburetor swaps, this is a cheap fix. It’s not for perfectionists who want OEM reliability – expect to tinker. For a weekend mower, it’ll work fine; for a commercial machine, buy the OEM Kohler carb ($50+).
