bought it on a total whim just to try out tuning my 2300 series carb differently, low expectations honestly, but the threads are clean and the matching sealing gasket did its job under high performance.

FAQs
What is the function of the power valve on a Holley?
A standard power valve opens under engine vacuum to deliver extra fuel enrichment during heavy acceleration or load conditions. Blocking it off with a plug eliminates this automatic enrichment for specific racing or custom tuning setups.
Why do people block off their power valve in a Holley 4150?
Engine builders and racers often block off the power valve to maintain consistent air-fuel ratios without unexpected enrichment spikes, particularly in high-performance or competition applications where primary jetting is precisely fixed.
What carburetor models are compatible with the Holley 26-36 plug?
This power valve plug is designed to fit Holley Model 2300, 4150, 4160, and 4500 series carburetors that feature matching 1/2-28 fine threads in the metering block power valve cavity.
