My machine was going along fine with the coins advancing in the escalator. Now when I pull the handle the coins stay and I can keep pulling the handle since the escalator did not move and all coins are in same spot but the wheels spun.
If I advance the escalator by hand a little it will work for a few coins but then I have to hold the handle down until the escalator slowly and real slowly it advances coins. Sometimes it works just perfectly for four or five coins then it doesn’t.

Any ideas how to fix?

It appears that the master chain link is binding up with the roller on the cam stop lever. Is there a fix?

Looks like the roller arm is too low. Remove it and put one or two washers under it where the stud is. Looks like it's hitting the chain.
