What It Is

This is an aftermarket complete carburetor assembly for Kohler 7000 Series V-twin engines (22–26 HP). It replaces the original carb on lawn tractors, zero-turns, and commercial mowers when the old unit is clogged, leaking, or not adjustable. Includes fuel pump, filter, lines, clamps, and gasket—everything needed for a swap.

Fitment & Compatibility

Check your engine model number (stamped on valve cover or blower housing). This carb fits Kohler KT725, KT730, KT735, KT740, KT745, and engines with OEM part numbers 16 853 21-S or 16 053 21-S.
Does not fit all 7000 Series engines—some use a different fuel pump or throttle linkage. Measure the mounting bolt spacing (typically 2.5” center-to-center) and compare the fuel line diameter (3/16” or 1/4”).
Brand/model of mower matters less than the engine itself, but common fits include Cub Cadet, John Deere, Husqvarna, Troy-Bilt, and Craftsman with Kohler 7000 Series engines. Confirm your carb has the same choke and throttle cable connections (some use a fixed jet vs. adjustable low-speed screw).

Key Things to Know

• Aftermarket quality varies: This is a budget carb. Expect some casting flash, slightly looser tolerances, and possible jet differences. Clean it before install—blow out all passages with compressed air.
• Installation is straightforward but requires adjusting the idle mixture screw (1.5–2 turns out from lightly seated) and checking for vacuum leaks. Use the included gasket; don’t overtighten the mounting bolts.
• Common gotcha: The fuel pump may not match your original’s pulse line location. You may need to reroute or extend the line. Some users report needing to swap the old fuel pump onto the new carb if the pulse fitting is different.
• Not adjustable for high-speed: Most 7000 Series carbs have a fixed main jet. If your engine runs lean at full throttle, you may need to rejet or buy a different carb.

Should You Buy It

Buy this if your original carb is beyond cleaning (hard starting, surging, or leaking) and you want a low-cost, complete swap for a Kohler 7000 Series engine. It’s a decent fix for a weekend mower, but expect to spend 30–60 minutes on adjustments. Skip it if you need exact OEM fitment, professional-grade durability, or have a non-standard linkage setup—spend $60–80 on a genuine Kohler carb instead.
