16-853-19S Carburetor Kit for Kohler 7000 Series KT725 KT730 KT735 KT740 KT745 22HP-26HP Engine | Replace OEM 32-853-67-S 32-853-63S | Complete Lawn Mower

What It Is

This is a complete carburetor kit for Kohler 7000 Series KT725, KT730, KT735, KT740, and KT745 engines (22–26 HP). It replaces the OEM carburetor assembly on residential and light-commercial zero-turn mowers, tractors, and stand-on mowers equipped with these engines.

Fitment & Compatibility

• Engine models: Kohler KT725, KT730, KT735, KT740, KT745 (check your engine tag—usually under the air filter or on the valve cover).
• OEM replacements: Directly swaps with Kohler part numbers 32-853-67-S and 32-853-63S.
• Machine fit: Fits any mower brand using these engines (e.g., John Deere, Cub Cadet, Husqvarna, Toro, Gravely, Bad Boy, Ariens).
• What to measure: The carburetor flange bolt pattern is standard for this engine series—no special adapters needed. Verify the fuel inlet orientation (side vs. bottom) matches your old unit.
• Warning: Does not fit KT610–KT620 or Courage series engines. Double-check your engine model number, not just the mower deck size.

Key Things to Know

• Quality: Aftermarket unit—generally good for the price, but some users report needing to clean out debris or adjust the float height before installation.
• Installation difficulty: Moderate. Expect to remove the air filter housing, throttle cable, fuel line, and two bolts. Have a gasket scraper and a small screwdriver handy.
• Common gotcha: The carburetor may be set lean from the factory. If your engine surges or bogs under load, adjust the main jet screw (typically 1.5–2 turns out) after installation.
• Warranty: No OEM warranty—buyer accepts risk of fitment or tuning quirks. Return policy depends on the seller, so confirm before ordering.

Should You Buy It

If your Kohler 7000 Series engine is hard-starting, surging, or flooding due to a gummed-up or failed carburetor, this kit is a budget-friendly fix. It’s best for DIY mechanics comfortable with basic small-engine tuning. Skip it if you need OEM warranty support or a drop-in-ready part without any adjustment—pay double for the genuine Kohler unit.
