The accelerator pump on my Zenith died over the winter. Found another Zenith NOS online, but it appears to have the same problem: the accelerator pump (see pic) is extremely hard to push down. It will pump gas when depressed but it takes like 10-15lbs of force. It returns just fine (and appears to pump gas in that direction too?). I assume that the pump plunger should be able to move with just the force of the long spring on its shaft?
The pic is of my old carb with an old overhaul kit in it (I think the blue plungers were silicone rubber maybe?)
