Balancing power and efficiency begins with the right fuel jet. The Stock Jet (SKU 555114) for Briggs Raptor engines, superseded by 692134, meters fuel precisely to match your kart's demands, preventing lean conditions that rob speed on straights.

  • Delivers consistent mixtures for reliable throttle response across RPM ranges.
  • Reduces carbon buildup, extending engine life for more track time.
  • Fits seamlessly into OEM carburetor rebuilds for hassle-free upgrades.

Competitive karting thrives on small tweaks— this jet allows you to optimize for track-specific conditions, like humidity or elevation, ensuring your flathead engine fires on all cylinders. Teams use it to organize parts inventories effectively, keeping spares ready for any race day scenario and focusing on what matters: crossing the finish line first.

Frequently Asked Questions

Q: Why has the 555114 jet been superseded by 692134?

A: Briggs & Stratton periodically updates part numbers to streamline inventory and improve manufacturing standards. The 692134 jet is the direct, updated replacement for the 555114, ensuring you receive the latest OEM specifications for your Raptor engine.

Q: How does changing the carburetor jet affect my kart's performance?

A: The jet controls the fuel-to-air ratio. A properly sized jet prevents "lean" conditions (too much air, not enough fuel) which can cause engine overheating and power loss, or "rich" conditions that lead to sluggish throttle response and carbon buildup.

Q: When should I consider changing my jet size?

A: You should adjust your jetting based on track-specific conditions such as elevation, humidity, and ambient temperature. Denser, colder air usually requires a larger jet to maintain the correct fuel mixture, while hot or high-altitude conditions may require a leaner setup.

Q: Is this jet compatible with other Briggs engines like the LO206 or Animal?

A: No, this specific jet is designed for the Raptor flathead engine series. The LO206 and Animal engines use different carburetor specifications and jetting requirements.

Q: What is the best way to maintain my carburetor jet?

A: Keep your jet clean by using high-quality fuel and a clean fuel filter. If you notice a drop in performance or erratic idling, remove the jet and inspect it for debris or varnish buildup, which can restrict fuel flow.
