LEIMO KPARTS 799727 is a direct-fit Nikki-style carburetor built to replace worn or damaged carburetors on Briggs & Stratton 14–18 HP Intek engines, restoring reliable fuel delivery and smoother engine operation.

This LEIMO KPARTS 799727 unit supersedes several OEM numbers and includes anti-backfire solenoid features and improved intake passages to improve airflow stability. It’s made to match the original mounting and linkage layout so hobbyist mechanics can install it without major modifications.

How does this carburetor improve engine performance?

The LEIMO KPARTS 799727 features redesigned air intake holes and an anti-backfire solenoid to stabilize fuel delivery and reduce sputtering on start-up or under load. Those changes help maintain a steadier idle and more consistent throttle response without altering engine tuning dramatically.

• Anti-backfire solenoid helps prevent ignition backflow and protects the carburetor base.
• Improved airflow passages minimize turbulence for steadier mixture distribution.
• Direct-fit linkage and mounting reduce chances of vacuum leaks after installation.
• Precision-machined ports for consistent fuel metering and idle stability.

What comes with the carburetor and what do I need for installation?

The 799727 carburetor is supplied as a ready-to-install Nikki-style unit. Basic replacement requires standard hand tools and a brief tune-up once fitted — cleaning the mounting surface, replacing gaskets if needed, and adjusting the idle mixture to match your engine.

• Carburetor arrives assembled with anti-backfire solenoid and factory-set components.
• You may need new gaskets, fuel lines, or clamps depending on your mower’s condition.
• Basic tools: screwdriver, socket set, wrench, and optionally a tachometer for precise idle setting.
• Inspect and replace compatible air filter elements (#797008, 698083, etc.) for best results.

Which filters and additional parts match this carburetor?

This carburetor pairs with several air filter and pre-filter part numbers commonly used on Intek engines, and it’s compatible with multiple Briggs & Stratton carb part numbers for interchangeability. Using fresh filters and correct seals reduces contamination and improves longevity.

• Compatible air filter references include 797008, 698083, 677014, 697634, 795115, 697153.
