799727 Carburetor Kit for Briggs & Stratton Intek 14-18HP OHV Lawn Mower/Lawn Tractor Engines, Replaces 698620/496796/499153/695412, w/Solenoid, Spark Plug, Air Filter & Kit Parts

What It Is

This is a complete carburetor replacement kit for Briggs & Stratton Intek 14-18HP OHV engines found on riding mowers and lawn tractors. It includes the carburetor, solenoid, spark plug, air filter, gaskets, and hardware to restore fuel delivery and starting.

Fitment & Compatibility

• Engine models: Briggs & Stratton Intek single-cylinder OHV engines with 14-18 HP (e.g., 31C707, 31P977, 33R877). Not for V-twin or older flathead engines.
• OEM numbers replaced: 698620, 496796, 499153, 695412. Verify your engine’s model/type/spec code on the valve cover or shroud.
• Measurements: Carburetor mounting flange spacing is 2.5 inches center-to-center. Check your old carb’s bolt pattern and fuel inlet orientation (side or bottom).
• Brand fitment: Universal aftermarket; may need minor gasket trimming or throttle linkage adjustment. Not an exact OEM fit for all Intek variants.

Key Things to Know

• Quality concerns: 3.0-star rating with only 3 reviews suggests inconsistent fit or performance. Expect thin gaskets, possible solenoid wiring differences, and a generic spark plug (likely J19LM or equivalent).
• Installation difficulty: Moderate – you’ll need to transfer the throttle/governor linkage, adjust idle mix screw (if present), and ensure the solenoid wire connector matches your harness. Some units ship with the solenoid pre-installed but not wired.
• Common gotchas: The included air filter may be too small for some Intek air cleaner housings. The spark plug gap may be pre-set incorrectly; always check and gap to 0.030 in. The solenoid may not be compatible with all Intek fuel shut-off systems.
• What’s missing: No fuel line, clamps, or carburetor mounting gaskets beyond the base gasket. You may need to reuse or buy separate intake manifold gaskets.

Should You Buy It

Buy this kit only if you’re comfortable with basic carburetor tuning and have a spare hour to tweak linkage and verify fit. It’s a budget stopgap for a non-critical mower, but for a reliable daily-use tractor, spend more on an OEM carburetor (e.g., Briggs 698620) to avoid fitment headaches and poor performance.
