What It Is

This is a complete carburetor replacement kit for Kohler 7000 Series KT engines (22–26 HP), including a carburetor, gaskets, air filter, oil filter, and spark plug. It’s designed for residential lawn tractors and zero-turn mowers using Kohler KT725, KT730, KT735, KT740, or KT745 engines.

Fitment & Compatibility

• Engine models: Kohler 7000 Series KT725, KT730, KT735, KT740, KT745 (22–26 HP). Not for Courage or Command series.
• OEM part numbers: Replaces 3285367S, 1685319-S, 3285363S, 853-50-S. Verify your engine’s OEM carb number stamped on the old unit.
• Deck size irrelevant – only engine model matters. Check your engine’s model/spec number (stamped on valve cover or shroud).
• Aftermarket: This is a non-OEM kit. Fitment is generally good but may need minor gasket trimming or adjustment of the float bowl nut.

Key Things to Know

• Installation difficulty: Moderate. Requires removing the engine shroud, disconnecting fuel lines, and swapping the carburetor. Expect 30–60 minutes. Not plug-and-play for beginners.
• Quality variance: Some users report needing to clean the new carburetor (debris in jets) or adjust the idle mixture screw. A small inline fuel filter is recommended.
• Kit contents: Includes air filter, oil filter, spark plug, and gaskets. The oil filter may not match OEM specs exactly – verify thread size (¾-16) and bypass valve rating.
• Common gotcha: The included air filter may be slightly shorter than OEM. If it doesn’t seal tightly, reuse your old filter or buy a genuine Kohler.

Should You Buy It

Buy this kit if you have a Kohler KT7000 series engine with a failing carburetor and want a budget-friendly all-in-one service kit. It’s best for DIYers comfortable with basic engine work; skip it if you strictly want OEM parts or have a non-KT7000 engine.
