Dominator HP #24 Air Bleed

The Holley Dominator HP #24 Air Bleed is a precision carburetor tuning component engineered for fine-fuel metering control in high-performance engine applications. This set of 10 brass air bleeds features a 0.024-inch (Number 24) internal diameter, allowing experienced carburetor builders and engine tuners to dial in precise air-fuel ratios across the idle and transition circuits of Holley four-barrel and two-barrel carburetors.

Air bleeds meter atmospheric air into fuel circuits, directly influencing idle quality, throttle response, and part-throttle drivability. The #24 size sits in the mid-range of Holley's air bleed lineup, making it suitable for carburetors on small-block and mid-sized engines where controlled fuel enrichment during off-idle conditions is critical. Brass construction provides corrosion resistance and dimensional stability, essential for maintaining calibrated fuel delivery over extended use. The compact 0.024-inch bore allows precise adjustment of emulsion characteristics without requiring full circuit replacement.

This product is designed for carburetor restoration, hot rod tuning, and performance engine builds where Holley carburetors are the platform of choice. Users rebuilding or re-jetting Dominator HP, Street Avenger, or other modern Holley carburetors will find the #24 air bleed essential for baseline tuning kits. The set of 10 provides enough components for testing multiple bleed combinations or servicing multiple carburetors without reordering.

Carburetor air bleeds are wear items and consumables in serious tuning workflows—having a stock of factory Holley bleeds ensures compatibility and eliminates guesswork when dialing carburetor behavior. Proper air bleed selection is foundational to achieving smooth idle, clean transition, and responsive throttle feel on any Holley carburetor platform.
