Which Kawasaki engines and model codes will this AUTOKAY carburetor fit?

The kit is made to replace OEM carburetors on many FH451V family engines and some FH500V variants. Check your engine code against the list below to confirm compatibility before purchase.

• Fits FH451V and FH500V engines using OEM references 15003-7036 or 15003-7033.

What parts are included in the AUTOKAY carburetor kit?

Rather than shipping only the carburetor body, AUTOKAY supplies a small-parts bundle so you can complete the installation without sourcing multiple components. This helps avoid delays and ensures mating surfaces and fuel lines match the new carburetor.

• One complete carburetor (15003-7036 or 15003-7033 depending on SKU).
• Two replacement gaskets to seal the intake and mounting surfaces.
• Fuel pipe and four clamps for secure hose connections.
• Inline fuel filter, small air filter and a fuel pump included for a thorough refresh.

How will installing this carburetor impact performance and routine maintenance?

Replacing a deteriorated carburetor with a new, properly matched unit restores predictable engine starting and idle behavior. While it won’t change engine specs, a fresh carburetor and new filters can reduce stalling, rough idling, and fuel delivery interruptions caused by leaks or clogged components.

• Improves cold starts and stabilizes idle if previous carburetor was leaking or clogged.
• New gaskets reduce air leaks that might cause lean running or surging.
• Included fuel filter and pump lower the chance of debris reaching the carburetor throat.

What should I verify before buying and installing this replacement?

Confirming part numbers, engine submodel, and the physical mounting orientation prevents fitment issues. Have basic hand tools and a torque reference handy; replace gaskets and clamps during installation to secure connections.

• Match your engine code to the compatibility list above before ordering.
• Inspect the throttle and choke linkages for wear and alignment during installation.
• Use supplied clamps on fuel lines and replace any cracked hoses for safety.

Who this is for: Technicians, small-engine repair shops, landscapers, and DIY owners of Kawasaki-powered mowers or equipment who need a reliable, ready-to-install carburetor replacement kit. It’s intended for users comfortable with routine engine service and basic mechanical installation; this kit saves time by bundling the small parts often required to complete a carburetor swap.
