Are you sure about what you bought? I've never seen a round Hypercharger. The scoopy, tunnel ram looking shape is what defines them.
Honestly, I'm not sure how you would even tweak a carb to run differently with the same jets. Restrict the fuel flow? Rejetting is how you adjust a carb when altering the air flow.
You might want to get a real clear picture of exactly what you're working with, and maybe post a couple photos. That's probably the best way to get the experts chiming in.
