SYOWADA 15004-0986 Carburetor Replacement For Specific Kawasaki Engines FR651V FS651V FR691V FS691V 23 HP Gravely ZT 42 XL, 15004-0828 15004-7062 Carburetor (Carburetor)

What It Is

The SYOWADA 15004-0986 is an aftermarket carburetor designed to replace the OEM carb on Kawasaki FR651V, FS651V, FR691V, and FS691V engines. It’s a direct fit for commercial-grade zero-turn mowers like the Gravely ZT 42 XL and similar models that use these 23 HP engines.

Fitment & Compatibility

Check your engine model number – stamped on the valve cover or blower housing. This carb fits only Kawasaki FR/FS 651V and 691V engines (not FR730V or other series). It replaces OEM part numbers 15004-0828 and 15004-7062.
Verify your mower brand – known to fit Gravely ZT 42 XL, but also works on many other zero-turns (e.g., Bad Boy, Hustler, Scag) with those Kawasaki engines.
Measure mounting bolt spacing – OEM is 2.5 inches center-to-center. Confirm your intake manifold and air filter housing match the carb’s 1.25-inch bore diameter.
No modifications required – gaskets and hardware are included, but keep your original fuel line and throttle linkage.

Key Things to Know

• Build quality – Metal body, but some users report thin gaskets. Consider replacing with OEM gaskets if you see leaks.
• Installation difficulty – Moderate. You’ll need to drain the fuel, remove the air filter housing, and swap throttle/governor linkage carefully.
• Adjustment needed – Idle and main mixture screws may require tuning after install. A tachometer helps set idle to 1800 RPM.
• Common gotcha – The included bowl drain screw can strip if overtightened. Use a torque wrench (8-10 ft-lbs).

Should You Buy It

If you have a Kawasaki FR/FS 651V or 691V engine and need a budget-friendly replacement for a worn or clogged OEM carb, this is a solid choice. It’s not as durable as a genuine Kawasaki part, but at this price it’s great for DIY repairs on older machines or seasonal mowers. Avoid it if you need exact OEM fitment for warranty work or commercial daily use.
