The Edelbrock single‑stage 2.5 in Hg power valve is a replacement power valve that uses engine vacuum to modulate fuel enrichment under load. It opens under heavy load to supply extra fuel to the main circuit, helping to prevent hesitation and bogging during acceleration. Use this standard‑flow valve to maintain smooth power delivery in compatible carburetor applications where a 2.5 in Hg opening is appropriate.
