125-65 power valves
The 125-65 power valves are an important component in the power enrichment circuit of Holley's performance carburetors. They operate by using engine vacuum to control their opening and closing rate. When they open, additional fuel is supplied to the main system during heavy load or under full power situations to eliminate hesitation and bogging--ensuring the smooth delivery of power without any drivability concerns. They're available in many different vacuum ranges to time the system's operation to your specific requirements, and they come in your choice of single-stage, two-stage, and high-flow designs.

Listing shows 2-port Power Valves and 4 washers. Items received are 4-port (higher flow) with just 2 washers. The higher flow Power Valves are NOT advised for stock engines, so these will NOT work for my application. Threads on these are NOT the same as on original item. See photos. Amazon won't return for credit. Do NOT buy these.

Product looked fine, but when tested they were not calibrated to the posted 6.5, function at a much lower pressure. Test what ever you buy don’t assume it’s set at posted number/pressure.
