Sorry to hear you're having trouble. It sounds like the spring might be too strong. You selected the 33D as your stamp option, but are you sure that's correct? Was this the number on your old balance, as well? If so, did you ever find that your windows were hard to operate in the past? Two S795-33 balances with a 33D option can carry a sash weight of 25 through 30 pounds. How heavy is your sash?
