What It Is

This is a complete aftermarket carburetor designed to replace the fuel system on Briggs & Stratton single-cylinder engines commonly found in riding mowers, zero-turn mowers, and garden tractors. It serves the 14hp to 18hp range, handling fuel metering and air mixture for those engines.

Fitment & Compatibility

Before buying, confirm your engine’s model number—not just the horsepower. This carburetor directly replaces OEM part numbers 698620, 791886, 495935, 690194, 498061, 499153, 496796, 287707, and 287777. It fits engine families 28N707, 28N777, 28P777, and 28Q777. Check the metal tag on your engine’s blower housing or valve cover for the model number. This is an aftermarket part, so it may not match OEM carburetor gasket or fuel line orientation exactly—measure the mounting stud spacing (typically 3.28 inches center-to-center) and the fuel inlet diameter (usually 1/4 inch) to verify. It will not fit vertical shaft engines or smaller push mower engines.

Key Things to Know

• Quality is acceptable for the price – Expect cast metal body and plastic float. It works well out of the box for most users, but some report needing to adjust the idle mixture screw slightly.
• Installation is straightforward – You’ll need a socket set, a flathead screwdriver, and possibly a new fuel filter. Remove the old carb, transfer the mounting gasket (or use the included one), and reconnect fuel and throttle linkage. Expect 20-40 minutes.
• Common gotcha: gasket fit – The included gasket may be slightly thinner or thicker than OEM. If you get a vacuum leak, reuse your old gasket or add a thin layer of gasket sealant.
• Warranty is limited – Hipa offers a 30-day return window. Test the carb immediately after installation; if it leaks or runs rough, swap it out.

Should You Buy It

This carburetor is a solid budget fix for a riding mower that won’t start, runs rough, or leaks fuel—provided you’ve confirmed your engine model number matches. It’s not built to OEM durability standards, but at under $20 it’s a low-risk replacement for a worn or clogged original. Best for DIY homeowners who want a quick, cheap fix rather than rebuilding the old carb.
