What It Is

This is an aftermarket carburetor and air filter gasket kit designed for Kohler Command PRO engines in the CV13–CV16S series. It’s used on lawn tractors, zero-turns, and commercial mowers to replace a worn or clogged carb that causes hard starting, stalling, or poor fuel delivery.

Fitment & Compatibility

Before buying, match your engine’s model number (e.g., CV15S, CV16S) stamped on the valve cover or blower housing. This carb replaces OEM part numbers 1285395-S, 12-853-58, 12-853-95-S, 12-853-83, and 12-853-08. The kit also includes the 12-883-10-S1 air filter gasket. It fits engines with a side-draft, fixed-jet carburetor design. Measure the mounting stud spacing (approx. 2.5 inches center-to-center) and check that your intake manifold gasket matches. This is an aftermarket part—not OEM Kohler—so verify your engine’s specific carburetor style (some CV models use a different bowl or choke linkage).

Key Things to Know

• Quality variance: Aftermarket carbs can have slightly leaner jetting or looser tolerances. You may need to adjust the idle mixture screw (if adjustable) or clean the jets before installation.
• Installation difficulty: Moderate. You’ll remove the air cleaner, disconnect fuel and throttle linkages, unbolt the old carb, and swap gaskets. Expect 30–60 minutes. A new gasket and air filter gasket are included.
• Common gotchas: The choke linkage may not align perfectly with your engine’s cable—bend it gently with pliers. Also, check the fuel line size (usually 1/4-inch) and replace old fuel if it’s gummed up.
• No tuning needed for fixed-jet models: If your engine uses a non-adjustable carb, this is a direct bolt-on, but you may need to clean the bowl or float if it sits on the shelf.

Should You Buy It

Buy this if you have a Kohler CV13–CV16S engine with a failing carb and want a budget-friendly replacement that includes the air filter gasket. It’s a solid value for DIYers who can handle minor adjustments, but if you need exact OEM fitment or have a commercial mower running daily, spend more on an OEM Kohler carb for better durability and jetting accuracy.
