just got a new (well, second-hand) engine in my '64 bug, but she's having some trouble idling at low revs. stalls a lot. i've adjusted the idling screw as far as it'll go, but it doesn't help; can anyone tell me exactly where the "volume control screw" is? it's marked on a diagram in the yellowed and fragmenting manual that came with the car, but the diagram doesn't actually tell you where the machinery is.
i know it's in the back somewhere.
