What It Is

This is a complete carburetor assembly paired with an air filter maintenance kit, designed for Kohler KT700 series engines (KT725, KT730, KT735, KT740, KT745). It’s a direct replacement for failing or clogged carburetors on riding mowers, tractors, and zero-turn mowers using these engines, typically found on brands like Cub Cadet, John Deere, Husqvarna, and Craftsman.

Fitment & Compatibility

Before buying, verify your engine model number (e.g., KT725-3048) stamped on the valve cover or engine shroud—not just the mower brand. This kit replaces OEM part numbers 16 853 19-S, 32 853 67-S, and 32 853 63-S. Measure the carburetor mounting flange bolt spacing (typically 2.5 inches center-to-center) and the air filter housing dimensions to match your existing setup. It fits most 18-26 hp Kohler Command Pro engines in the KT series, but not older Courage or single-cylinder models. Check that your mower’s throttle/choke cable linkage matches the carburetor lever positions—some may require minor adjustment.

Key Things to Know

• Quality varies: This is an aftermarket carburetor, not OEM Kohler. Expect potential fitment issues with gaskets or air filter alignment—some users report needing to reuse original gaskets or trim the filter.
• Installation difficulty: Moderate. Requires removing the old carburetor, swapping linkages, and synchronizing the throttle and choke cables. Have a small screwdriver set and carburetor cleaner handy.
• Common gotcha: The included air filter may not match your housing exactly—check dimensions before installing. Also, the carburetor may need a minor adjustment of the idle mixture screw (1.5 turns out as a starting point) to prevent surging.
• No warranty support: This is a budget part; expect to troubleshoot yourself. If your engine has a fuel solenoid, verify the new carburetor includes one or can accept your old solenoid.

Should You Buy It

Buy this if you have a Kohler KT700 series engine with a worn or clogged carburetor, you’re comfortable with basic small-engine repair, and you want a low-cost fix rather than a $100+ OEM part. It’s a solid budget option for DIYers, but skip it if you need exact OEM fitment, lack mechanical confidence, or your mower is under warranty—go with a genuine Kohler replacement instead.
