Control the flow with finesse: In Briggs Raptor engines, the Adj. Needle Spring (SKU 555123)—superseded by 691592—applies just-right pressure to the needle, facilitating easy dialing of your fuel mix. This prevents over-fueling that drags speed or starving that causes hesitation.
- Offers consistent resistance for repeatable settings.
- Endures repeated adjustments without losing shape.
- Essential for Raptor OEM carb precision.
Racers integrate it into their trackside organization, swapping springs to match engine mods for personalized power curves. Feel the difference as your kart accelerates more predictably, turning technical tracks into opportunities for personal bests.
