New Carburetor Replacement for Kohler CV12.5 CV13S CV13T CV14 CV14S CV15S Carb CH11 CH13 CH14 CH15 11hp 13hp 14hp 15hp Engines

What It Is

This is an aftermarket carburetor designed to replace the OEM unit on Kohler Command and Courage single-cylinder engines in the 11–15 hp range. It’s intended for lawn tractors, zero-turns, and other small-engine equipment using Kohler CV12.5, CV13S, CV13T, CV14, CV14S, CV15S, CH11, CH13, CH14, or CH15 engines.

Fitment & Compatibility

• Engine models only – Works with the listed Kohler CV and CH series. Does not fit Kohler twin-cylinder, vertical-shaft, or non-Command/Courage engines.
• Check your engine’s spec number – Kohler engines with the same series number (e.g., CV13S) may have different carburetors depending on the spec suffix. Cross-reference your old carb’s part number (often stamped on the side) with the listing.
• Measure bolt spacing – OEM carb mounting holes are typically 2.5″ center-to-center. Verify your intake manifold gasket matches.
• Aftermarket vs. OEM – This is not a Kohler genuine part. Gaskets, jets, and choke linkage may differ slightly. Expect to reuse your original choke cable and throttle linkage.
• Included parts – Usually comes with a gasket set and sometimes a fuel line. Confirm before buying.

Key Things to Know

• Quality varies – Many users report it works out of the box, but a small percentage get a unit with debris in the bowl or a misaligned float. Inspect and clean before installing.
• Jetting may be off – If your engine runs lean (surges at idle) or rich (smokes), you may need to swap the main jet with your old one. Keep the original carb for parts.
• Installation is straightforward – Requires basic hand tools (socket set, screwdriver) and about 30 minutes. Take photos of linkages before removal.
• Fuel compatibility – Ethanol-blended gas can degrade aftermarket gaskets faster than OEM. Use fuel stabilizer or non-ethanol fuel if possible.

Should You Buy It

If your Kohler engine’s original carb is clogged, leaking, or unrepairable and you want a budget fix for a mower that’s not a collector piece, this is a solid choice. It’s not for pros needing zero downtime—expect occasional tweaking. For the price, it’s worth a try if you can return it if defective.
