I really don't understand making a line of carbs that can't be used with the pump you make.
I'd have designed the regular carbs to be used with or without the pump. The difference being that the pump carbs would have a over sided venturi for more power.
They do make pump calibrated carbs in nearly every size, you just selected the wrong carb. You can't return the one you have for the one you need?
Pump carbs always have metering calibrated to work with the pump, OS, webra, perry, etc.
