Needle Adjustment Assembly Seal for Briggs Raptor Carbs - Superseded by 691608

Precision fueling demands tight seals—the needle adjustment assembly seal (SKU: 555106) provides it. For Briggs Raptor carbs, superseded by 691608, this rubber ring encircles the adjuster to block leaks.

• Viton material handles fuel and temps
• Allows smooth needle tweaks without binding
• Stabilizes idle and part-throttle response

Leaking seals flood bowls or starve jets; this keeps balance, promoting crisp power delivery for every gear shift. It streamlines tuning sessions, organizing your carb work for race-ready results.

Essential for avoiding rich runs that slow you down, it elevates overall engine harmony.
