How many leaks do you have?

Leaking around the throttle shaft I would think would be normal, depending how much gas your poured down the carb and if the throttle was closed. If the throttle shaft is sloppy you need bushings. You don't want much more than a couple of 32nds slop. There is not much clearance around the butterfly.

Are you sure the hole that is leaking isn't vacuum port that might have lost the tube to put a hose on?
