Gas leaking at the throttle valve shaft comes from a flooding condition. That could have just been a stuck float or needle and seat not closing. The needle is usually made with a resilient tip which can deteriorate and allow flooding to occur. It doesn't necessarily mean that the shaft/bore are all that worn, since there has to be some clearance for the shaft to move, and gas will wick right on thru that small a crack. A kit isn't that expensive, so maybe throwing a kit at it will work just fine. It's already off, so take it apart and see what's inside before you buy a kit.
