• Replaces Kawasaki part numbers: 15004-0986, 15004-0828, 15004-7062

• Matches factory mounting bolt pattern and throttle linkage positions
• Works with Gravely ZT 42 XL mower installations

What performance improvements should I expect after installation?

When an engine has symptoms like hard starting, surging, low power or rough idle due to a worn or clogged carburetor, replacing it with a correctly matched unit can re-establish proper fuel/air mixture and throttle response. This SYOWADA replacement is intended to restore predictable idling, smoother throttle transitions and improved engine responsiveness under load.

• More consistent idle and easier cold starts
• Smoother acceleration and reduced engine surging
• Improved fuel metering for steady power delivery
• Replaces degraded internal jets and valves in one swap

How straightforward is the installation process?

Installation is generally straightforward for anyone comfortable with small engine maintenance. The carburetor uses the same bolt pattern and connections as the original part, so it typically requires only basic hand tools and attention to throttle and choke linkage alignment.

• Simple bolt-on replacement; no major modifications required
• Verify throttle/choke linkage alignment before tightening
• Inspect fuel lines and gaskets; replace if brittle or leaking
• Recommended: clean mating surfaces and test-run for leaks

What should I check before ordering to ensure compatibility?

To avoid fitment issues, confirm both your engine model code and the original carburetor part number. Many small differences in throttle linkage, choke type or breather locations can exist between model years, so matching the engine code (FR651V, FS651V, FR691V, FS691V) and the original part number ensures the correct SYOWADA unit is purchased.

• Confirm engine model code stamped on the engine housing
• Compare original carburetor part number with 15004-0986 / 15004-0828 / 15004-7062
• Note choke type (manual vs. automatic) and linkage orientation
• Have basic tools and replacement gaskets on hand for installation

Who is this for: This SYOWADA carburetor is aimed at mower owners, small-engine technicians and fleet maintenance teams who need a reliable, direct-fit carburetor replacement for Kawasaki 23 HP FR651V/FS651V/FR691V/FS691V engines, particularly those used in Gravely ZT 42 XL equipment.
