FR691V Carburetor for Kawasaki FR691V FS691V FR691V-CS10 FR691V-CS12 | Fit Kawasaki FR691V-CS13 FR691V-CS14 Engine w/Part 150040985 150041063 15004-0829 15004-7063

What It Is

This is a replacement carburetor for Kawasaki FR691V series engines, commonly found on zero-turn mowers, riding mowers, and commercial lawn equipment. It delivers the fuel-air mixture to the engine and fixes symptoms like hard starting, stalling, or poor performance.

Fitment & Compatibility

Check your engine model – This carb fits Kawasaki FR691V, FS691V, and specific sub-models: CS10, CS12, CS13, CS14. It replaces OEM part numbers 150040985, 150041063, 15004-0829, and 15004-7063. Do not rely on mower brand alone – verify the engine model number (stamped on the valve cover or blower housing). This is an aftermarket part, not OEM Kawasaki. Measure the carb mounting hole spacing (typically 60mm) and bowl diameter (about 2.5 inches) to confirm physical fit. Not compatible with FR730V or other Kawasaki V-twin series.

Key Things to Know

• Quality varies – At $30, this is a budget aftermarket carb. Expect plastic or cast metal parts; some may need light deburring or gasket trimming.
• Installation difficulty – Moderate. Requires removing the air filter housing, fuel line, and throttle/governor linkages. Keep the original linkage springs – aftermarket ones often don’t fit.
• Common gotchas – The float bowl may be over-tightened from the factory; check the float height (usually 15-17mm). Use the old gaskets if the new ones leak. Adjust the idle mixture screw (typically 1.5-2 turns out) after install.
• No warranty support – With only one review, buyer beware. Test immediately; return window may be short.

Should You Buy It

This carb is a good option if you need a cheap, quick fix for a non-running FR691V engine and are comfortable with minor adjustments. Not for commercial use or if you want OEM reliability – for daily mowing, spend more on a genuine Kawasaki or high-quality aftermarket like Stens or Oregon.
