15004-0985 Carburetor for Kawasaki FR691V FS691V FR651V FS651V 23HP Engine Lawn Mower Toro MX 5000 TimeCutter 15004-0829 15004-7063 With Fuel Pump Air Filter Carb Tune Up Kit

What It Is

This is a complete carburetor replacement kit for Kawasaki FR691V, FS691V, FR651V, and FS651V 23HP engines, commonly used in Toro MX 5000 and TimeCutter zero-turn mowers. It includes the carburetor, fuel pump, air filter, and gaskets—everything needed for a full fuel system tune-up in one box.

Fitment & Compatibility

Before buying, confirm your engine model is one of these: Kawasaki FR691V, FS691V, FR651V, or FS651V (check the sticker on the engine valve cover). This kit replaces OEM part numbers 15004-0829 and 15004-7063. It’s designed for Toro MX 5000 and TimeCutter models, but also fits many other brands (e.g., John Deere, Cub Cadet) using the same Kawasaki engine. Measure the carburetor mounting flange (about 2.5" x 2.5") and fuel inlet diameter (5/16") to verify physical fit. This is an aftermarket kit—not OEM Toro—so expect slight cosmetic differences but functional compatibility.

Key Things to Know

• Installation difficulty: Moderate. You’ll need basic tools (screwdrivers, wrenches) and about 45–60 minutes. Remove the old carb, transfer the throttle/choke linkage, and attach the new fuel pump.
• Quality note: Aftermarket carburetors can vary. This kit generally works well, but some users report needing to adjust the idle mixture screw (turn 1.5–2 turns out from seated) for smooth running.
• Common gotcha: The included fuel pump may have different barb angles than OEM—check clearance to the engine shroud before tightening. Also, clean the fuel tank and line before installation to prevent debris from clogging the new carb.
• What’s included: Carburetor, fuel pump, air filter, gaskets, and mounting hardware. No spark plugs or oil filter—those are sold separately.

Should You Buy It

Buy this if your Toro or Kawasaki-powered mower is hard-starting, surging, or dying under load and you want a complete, cost-effective tune-up kit under $35. It’s a solid choice for DIYers who can handle basic carb work and don’t need OEM branding. Skip it if you’re uncomfortable with linkage adjustments or prefer genuine Kawasaki parts for warranty concerns.
