Advice needed

I noticed on the 2nd night with the new worm if my mount is well balanced I am getting oscillating autoguiding errors. If I slide the counterweight down a bit more it turns off and goes accurate. But if I slide it down too much it can stall the slews. I turned down the slew rate.

Do you think I may not have gotten the correct tension on the belt that drives the worm?

It did not oscillate before when in close balance. I mean its not too big of a deal as I can simply keep some weight on the balance to the west which is a common advice but this is belt drive not gear drive.?

Greg.
