MDAIRC Carburetor Kit for Briggs & Stratton 14–18HP Intek Engines — Model 799727 with Air Filter & Repair Parts

The MDAIRC 799727 carburetor kit is a direct-replacement overhaul assembly built to fit select Briggs & Stratton 14–18HP Intek engines, supplied with gaskets, fuel fittings, an air filter and essential service parts to restore fuel delivery and idle control.

If your mower, generator, or small engine with a Briggs & Stratton 14–18HP Intek motor runs rough, stalls at idle, or leaks fuel, a worn or clogged carburetor is often the culprit. This kit replaces OE numbers such as 791886, 698620, 690194 and compatible model carbs like 28N707, 28P777 and related part families. The package includes one carburetor plus mounting gaskets, shut-off valve, fuel line and filter, spark plug, oil filter and repair components to simplify on-machine installation and basic troubleshooting.

Will this carburetor fit my Briggs & Stratton Intek 14–18HP engine?

Fitment is determined by engine model and the original carburetor OE reference. The 799727 assembly is designed to replace common Briggs & Stratton part numbers and model families used on 14HP–18HP Intek engines.

• Replaces OE# 791886, 698620, 690194, 499153, 498061 and related numbers.
• Compatible with carb model families: 28N707, 28N777, 28P777, 28Q777 and many 28/31/40x series.
• Meant for Intek 14HP–18HP engines; verify your engine’s model and OE stamp before ordering.

How does this kit help with poor idling or stalling?

A fresh carburetor and included service parts address common causes of rough idle such as blocked jets, sticking float valves or contaminated fuel passages. Replacing the carb and cleaning or swapping the supplied fuel filter and lines restores consistent fuel flow and allows correct idle adjustment.

• New metering components and gaskets restore correct fuel/air mixtures for steady idle.
• Included shut-off valve and fuel filter reduce contamination and vapor lock issues.
• If idle stays low, the kit supports a simple screw adjustment (clockwise increases idle by small increments).

What troubleshooting tips should I follow after installation?

Several simple checks can prevent recurring problems: ensure the oil/fuel circuits are unobstructed, confirm the carb’s vacuum/negative-pressure port is clear, and check tubing for kinks or debris. These steps eliminate external causes before tuning jetting or idle settings.

• Verify oil supply line and fuel line are free and not pinched or blocked.
• Inspect the carburetor’s negative pressure hole for blockage if the engine stalls during shutoff.
• Use the supplied gaskets and follow torque recommendations to avoid air leaks at the mounting flange.

What parts are included and what will I still need?

The kit ships with the main carburetor and common consumables to simplify a one-stop replacement job. You may still need basic hand tools and, depending on engine condition, additional seals or a manifold gasket not included.

• Included: 1x carburetor, 4x mounting gaskets, shut-off valve, fuel line, fuel filter, fuel valve, spark plug, oil filter (492932), repair kit (796184) and an air filter set.
• Recommended: basic hand tools, gasket sealant (if required), and engine-specific manifold gasket if your original is damaged.
• Always compare included parts to your existing components for compatibility before installation.
