Power Valve Restrictors at Minnie Wilkin blog

Power Valve Restrictors. There are two of these restrictors located underneath the power valve. On all holleys there are two power valve channel restrictors (pvcr) that determine the amount of fuel delivered to the boosters. The power valve circuit uses a dedicated restrictor that determines the amount of fuel delivered when the power valve opens. Holley calls this a power valve circuit restrictor (pvcr).

It seems like having a secondary power valve is not only redundant but also potentially harmful if it is opening and closing during near wot and likely changing the a/f mixture. These restrictors are like a second pair of jets feeding fuel to the main metering well but only when the power valve opens. If the main jets feel right and the engine is too rich under full throttle, then you can also reduce the size of the channel restrictions. The pvcr is sized differently depending upon carburetor metering requirements.
