Baler knotter update

When I turn the machine by hand, both knotters seem to be exactly the same...no visible difference at any point during the knotting process. But the rebuilt knotter makes a perfect knot, and the old right knotter makes one that hangs on the hook.

But when I start the baler engine and run the baler at normal speed the results are reversed: the right knotter made 4 perfect knots on real bales while my rebuild formed 4 knots that did not release and (new problem) one side of the twine breaks just at the knot...this is the piece that goes back over top of the bale and down and below.

So I think maybe I'm getting a little closer, but still not there.

Any ideas now?

thanks,
Tom
