What It Is

This tune-up kit replaces the carburetor and related gaskets/filters on Kawasaki FR691V and FS691V 4-stroke engines, commonly found on Toro TimeCutter MX 5000 riding mowers (models 74772, 75750, 75759) and similar zero-turn mowers. It restores fuel delivery and air/fuel mixture after clogging or wear.

Fitment & Compatibility

• Engine match: Only for Kawasaki FR691V or FS691V (check engine model number stamped on shroud near spark plug). Not for FR651V, FS730V, or other Kawasaki V-twin variants.
• OEM cross-reference: Replaces Kawasaki part numbers 15004-0829, 15004-0985, and 15004-7063. Verify your current carburetor gasket set matches these numbers.
• Toro model fit: Confirmed for Toro 74772, 75750, 75759. For other Toro models (e.g., TimeCutter SS, MX 5060), measure carburetor mounting flange bolt spacing—should be 2.5" center-to-center.
• Deck size irrelevant: This part fits the engine only; deck size (42", 50", 60") doesn’t affect compatibility.
• Aftermarket note: This is a non-OEM (aftermarket) kit. May include slight differences in gasket thickness or jetting; compare old and new parts side-by-side.

Key Things to Know

• Installation difficulty: Moderate. Requires removing air filter housing, fuel lines, and throttle/governor linkage. Have a small flathead screwdriver and pliers handy.
• Common gotcha: The carburetor bowl gasket may be slightly thicker than OEM—tighten bowl screws evenly to avoid leaks. Use a torque wrench at 5-7 in-lbs if possible.
• Quality check: Kit includes carburetor, gaskets, fuel filter, and spark plugs. Some users report the included spark plugs are generic—consider swapping with OEM NGK BPR5ES for reliability.
• Tuning needed: After install, adjust idle speed and mixture screws (if adjustable) per Kawasaki spec (idle screw 1.5 turns out, mixture screw 2.5 turns out). Expect minor surging if not dialed in.

Should You Buy It

If your FR691V/FS691V is hard-starting, surging, or leaking fuel, and you’re comfortable with basic engine work (30-45 minutes), this $28 kit is a solid value versus a $100+ OEM carburetor. Best for Toro TimeCutter MX 5000 owners who want a drop-in fix without rebuilding the old carb. Avoid if you prefer OEM parts for warranty or if your engine has internal damage (e.g., bent valves)—then a full engine rebuild is needed.
