What It Is

This is a complete carburetor kit designed to replace the original equipment carburetor on Kohler 7000 Series KT725, KT730, KT735, KT740, and KT745 engines (22–26 HP). It’s for riding lawn mowers, zero-turn mowers, and other equipment using these Kohler twin-cylinder engines.

Fitment & Compatibility

Before buying, confirm your engine model is one of these: KT725, KT730, KT735, KT740, or KT745. The kit replaces OEM part numbers 16-853-19S, 16 853 19-S, and 32 853 63-S. Check the engine tag (usually stamped near the oil fill or under the air filter cover) for the exact model number—not just the horsepower. This is an aftermarket carburetor, not genuine Kohler. Measure the existing carburetor mounting flange bolt spacing (typically 2.75" center-to-center) to confirm physical fit. Not compatible with Kohler Courage or other series.

Key Things to Know

• Quality variance: Aftermarket carb kits may need minor adjustment to the idle mixture screw or float height. Expect to tune it slightly after installation.
• Installation difficulty: Moderate. You’ll need basic hand tools, a new gasket (usually included), and fuel line pliers. Plan 45–60 minutes.
• Common gotcha: The included fuel inlet fitting may be a different size than your existing fuel line. Have a small piece of 1/4" fuel line or a barb adapter on hand.
• Warranty: Most sellers offer 30-day return but no long-term guarantee. Check the return policy before buying.

Should You Buy It

This kit is a good budget option if your Kohler 7000 Series engine has a clogged or damaged carburetor and you’re comfortable with basic engine tuning. It’s not for someone who wants a drop-in replacement with zero adjustment—expect to tweak the idle and possibly the float level. For professional use or if you need guaranteed reliability, stick with the OEM Kohler carburetor.
