So changing squirter size is not the same as changing the diaghram?

So which should I change...the 50cc diaphram and cam......or the shooter?


When you change the squirters you end up changing how long the fuel squirts through them, not how much by volume, just the time it squirts out If you enlarge the squiter isze it will stop squirting sooner than when it has smaller squirters in it. If you want to reduce the volume used per stroke on the accelerator pump circuit change from the larger pump,50 CC, to the smaller 30 CC pump Holley, for what ever reasons, uses ten stroke on each pump to distingish(SP?) the differences between the 30 CC and the 50 cc pumps, it is not pumping 30 CC or 50 CC per pump shot
