Monkey Aligator theme, Nishijin, model B.
I have a Monkey Aligator model B. It seems the monkey may be held in up position by a weighted string over a pully and when ball goes in upper center pocket it lands on the monkey's head, pushes him down where when the monkey ia st the bottom in the open mouth of the aligator the ball rolls off the monkey's head into the aligator's mouth, releasing weight from monkey allowing him to "climb"the palm just as the ball causes the jaws to close just missing monkey's butt as it pushes down to roll to the payoff ramp. Pa Chinko.

My monkey won't climb.
The string is broken and I don't know how to begin to get to the area in center where it hangs over the pulley (I guess) so I can re-attach it.
Help me if you can. Thanks!
