Greetings everyone, I'm in the midst of an engine swap for my 1947 Plymouth and I'm needing some help with my starter. Upon close inspection, it seems like the bendix/screw shaft isn't fully retracting. As you can see in the picture, that's as far down as it will go, maybe a quarter inch. Should it freely move all the way down the screw? The annoying thing is I can't see what's preventing it from moving. Thanks in advance!
