Holley 1920 Metering Blocks?

This carb was on a souped up '64 Dart that looked like it was mildly customized in the 80's. I did get a whole exhaust from manifold to glasspack off of it so that was cool hahaha. For some reason the little linkage for the the accelerator pump was set on the last hole for the largest shot of gas. When I rebuilt it I just put it on the middle hole since most of the carbs I've had were in the middle. I wonder if I should have left it alone?
