I have been using (and enjoying) my Vendo 39 for the last couple of weeks, but have noticed a problem with the coin mechanism.  It sticks on free vend after a few vend cycles.  After searching old threads here I discovered what I think may be the problem.  The dog (10ยข coin mech) that locks up the ratchet spindle doesn't have a spring.  It should have one correct?  I ask because people have posted pictures on this site of their coin mechanisms and some appear to have the spring and some haven't been visible to me.
How would I go about getting one if that's what I need?  I hope its as simple as the local hardware store//
