15004-0985 Carburetor for Kawasaki 15004-0829 Fits Specific FR691V FS691V Engine Tune Up Kit

What It Is

This is an aftermarket carburetor and tune-up kit designed for Kawasaki FR691V and FS691V engines, commonly found in zero-turn mowers, lawn tractors, and commercial stand-on mowers. It replaces the OEM Kawasaki part 15004-0829 and includes the carburetor, gaskets, fuel filter, and spark plug for a full service refresh.

Fitment & Compatibility

• Engine models: Kawasaki FR691V (e.g., FS691V, FH691V variants). Check your engine’s model number stamped on the valve cover or shroud—must be a 691cc V-twin.
• OEM cross: Direct replacement for Kawasaki 15004-0829 and 15004-0985. Does not fit Kawasaki FS651V, FS730V, or other engine series.
• Mower brands: Used on many John Deere, Husqvarna, Toro, Exmark, Bad Boy, and Gravely zero-turn models. Verify your engine model, not just mower brand.
• Measurements: Carburetor mounting flange pattern is standard for these Kawasaki V-twins. No modification needed if your engine uses a side-draft carb with a single fuel inlet and electric choke.
• Kit contents: Includes carburetor, carb-to-intake gasket, air filter gasket, fuel filter, and spark plug. Does not include air filter element or fuel line.

Key Things to Know

• Quality variance: Aftermarket carburetors often have slightly leaner factory jetting than OEM. If you notice surging or poor idle, you may need to adjust the idle mixture screw (turn out 1.5-2 turns from fully closed).
• Installation difficulty: Moderate. You’ll need basic hand tools (sockets, screwdrivers) and a torque wrench for carb bolts (8-10 ft-lbs). Expect 30-60 minutes on a clean engine.
• Common gotchas: The included spark plug may be a lower-heat range than OEM—consider reusing your old plug if it’s in good condition. Also, the gaskets are thin; do not over-tighten or they’ll leak.
• Fuel system prep: If your old carb failed due to ethanol varnish, drain the tank and replace the fuel line before installing this kit.

Should You Buy It

Buy this if you need a budget-friendly repair for a Kawasaki FR691V/FS691V engine that runs rough, won’t start, or has a clogged carburetor—and you’re comfortable with minor adjustments. It’s a solid value for DIYers and small shops, but skip it if you demand OEM precision for commercial daily use.
