Carburetor Carb Kit for Kawasaki 15004-0985 Carb Fits Specific FR691V FS691V 15004-0829

What It Is

This is an aftermarket carburetor kit designed to replace the OEM Kawasaki 15004-0985 assembly. It handles fuel metering and delivery for Kawasaki FR691V and FS691V engines, commonly found on zero-turn mowers, garden tractors, and commercial walk-behinds.

Fitment & Compatibility

Before buying, confirm your engine model is FR691V or FS691V (check the stamped code near the blower housing or valve cover). This kit also cross-references to OEM part 15004-0829, so verify your current carb’s part number. It does not fit FR730V, FS730V, or smaller V-twin Kawasaki engines. Measure your carburetor mounting flange—this kit is for the standard 2-bolt pattern with 60mm spacing. If your mower has an electric PTO clutch or fuel pump, ensure the carb’s fuel inlet and primer bulb match your existing setup (some variants have angled vs. straight outlets).

Key Things to Know

• Quality variance: Aftermarket carb kits often have slightly thinner gaskets and less precise float settings. Expect to adjust the idle mixture screw (1.5–2 turns out initial) and check for fuel leaks at the bowl gasket.
• Installation difficulty: Moderate. You’ll need to remove the air filter housing, fuel lines, and throttle linkage. Use a torque wrench on the mounting bolts (8–10 ft-lbs) to avoid warping the intake.
• Common gotcha: The included fuel line may be too short or a different inner diameter (5/16” vs. 1/4”). Measure your existing lines and reuse them if possible.
• Primer bulb compatibility: Some kits ship with a bulb that doesn’t seat fully in the air cleaner base. Test fit before final assembly.

Should You Buy It

If your original Kawasaki carb is clogged or leaking and you’re comfortable tuning a small engine, this $26 kit is a cost-effective fix. It’s not a direct OE-quality drop-in—expect to tweak the mixture and gaskets—but it’s fine for non-commercial use or as a temporary replacement. Skip it if you need exact OEM fitment or warranty compliance.
