15004-0985 Carburetor Kit for Cub Cadet ZT1 ZT2 RZT50 John Deere X320 X380 X324 Husqvarna Z254f Toro SS-5000 SS-5050 Lawn Mower for Kawasaki FR651V FR691V FR730V FS730V 4-Stroke Engines

What It Is

This is a complete carburetor kit designed to replace the OEM unit on 4-stroke Kawasaki FR651V, FR691V, FR730V, and FS730V engines. It fits zero-turn and riding mowers from Cub Cadet, John Deere, Husqvarna, and Toro, restoring fuel delivery and engine performance.

Fitment & Compatibility

• Engine verification: Confirm your engine model (printed on valve cover or engine shroud) matches FR651V, FR691V, FR730V, or FS730V. This kit does not fit other Kawasaki series (e.g., FH or FS non-V).
• Machine cross-reference: Compatible with Cub Cadet ZT1, ZT2, RZT50; John Deere X320, X324, X380; Husqvarna Z254f; Toro SS-5000, SS-5050. Check your mower’s parts diagram for OEM part number 15004-0985.
• Deck size & year: No deck-size limitation, but ensure your mower uses the specific Kawasaki V-twin listed. Older models (pre-2010) may use a different gasket set.
• Aftermarket note: This is a direct replacement—no modifications needed. Gaskets, O-rings, and fuel inlet fitting included.

Key Things to Know

• Quality: Aftermarket but well-reviewed. Gaskets may be slightly thinner than OEM; use a thin layer of gasket sealant if you see leakage.
• Installation difficulty: Moderate. Expect 30–60 minutes. You’ll need to remove the air filter housing, fuel line, and throttle/choke cables. Label cables to avoid mix-up.
• Common gotcha: The kit includes a new fuel inlet fitting—ensure it’s fully seated and tightened. A loose fitting causes air leaks and hard starting.
• Tuning: You may need to adjust idle and mixture screws after install. Use a tachometer for precise idle speed (typically 3300–3400 RPM no-load).

Should You Buy It

If your Kawasaki FR-series engine runs rough, surges, or won’t start, and you’re comfortable with basic carburetor work, this kit is a solid, cost-effective fix. It’s not for worn-out engines or if you need OEM exactness, but for most DIY repairs it delivers reliable performance at half the dealer price.
