RADHLBNIU 24-853-102-S is a drop-in carburetor kit designed to replace the original Kohler carburetor on CV730, CV730S, CV740 and CV740S 25–27HP engines.

If your Kohler-powered mower, generator, or small equipment is running rough, leaking fuel, or failing to start, this replacement carburetor kit contains the key components to restore reliable fuel delivery without pricey dealer service. The kit is built as a direct-fit swap for engines that use Kohler part numbers and includes several installation-ready parts to make the repair straightforward for a competent DIYer or mechanic.

Will this carburetor fit my Kohler CV730 or CV740 engine?

Yes — the RADHLBNIU 24-853-102-S kit is made to match the mounting and fuel connections of Kohler CV730, CV730S, CV740 and CV740S high-torque engines (commonly used in 25HP and 27HP equipment). Check your engine model stamped on the valve cover and compare part numbers before ordering.

• Replaces Kohler part 24-853-102-S (and equivalent listed numbers)
• Compatible with CV730/CV730S and CV740/CV740S variants
• Intended for 25HP and 27HP engine configurations
• Direct bolt-on design that aligns with factory mounting points

What is included in the replacement kit and why each piece matters?

The package contains the carburetor plus several fuel-system parts that commonly fail or are replaced during a carb rebuild. These extras reduce the chance of repeat trips to the parts store and help ensure a complete, leak-free installation.

• 1 x carburetor (24-853-102-S compatible) to restore proper air-fuel mixture
• 1 x fuel pump for steady fuel delivery and pressure regulation
• 1 x air filter to prevent debris from entering the engine
• 1 x fuel shut-off valve for safe fuel isolation during storage
• 3 x gaskets and 4 x clamps to guarantee sealing and hose retention
• 1 x fuel line for immediate hose replacement and secure connections

How difficult is installation and what should I prepare?

Installation is intended to be straightforward: the kit is a direct replacement that uses existing bolt locations and fuel hookups. Basic hand tools, some thread sealant for fittings, and a clean work area are usually all that’s required; allow time for fuel system priming and leak checks after fitting.

• Tools needed: standard wrench set, screwdrivers, pliers, and possibly a torque wrench
• Work steps: drain fuel, remove old carburetor, swap gaskets, mount new unit, connect fuel pump/line
• Post-install checks: inspect for leaks, verify choke/throttle operation, start and adjust idle if necessary
• If in doubt, consult a service manual or a qualified small-engine technician

How long can I expect this replacement to last and how to maintain it?

Longevity depends on operating conditions and maintenance habits; using clean fuel, replacing the air filter regularly, and storing equipment with the fuel shut-off engaged will extend service life. The kit’s components are selected for durability and sealing to reduce common failure modes like leaks and clogged passages.

• Use fresh, clean fuel and a fuel stabilizer for seasonal storage
• Replace the air filter per manufacturer schedule or when visibly dirty
• Check clamps and hoses periodically for cracks or looseness
• Perform a routine tune-up: inspect spark plugs, ignition timing, and valve clearances

Who is this for: The RADHLBNIU 24-853-102-S carburetor kit is aimed at owners and technicians maintaining Kohler CV730/CV740 family engines in lawn tractors, garden equipment, or small commercial machines. It’s a good fit for DIY repairers who want a complete, direct replacement kit with the common consumables included, and for service shops seeking a cost-effective alternative to OEM-only sourcing.
