It doesn’t change anything. But when you described this, that’s the make and model I thought it was. For some reason, the older ones all developed this problem. However, I just addressed this same problem on a 30 year old style 30. I had to remove all of the rods, clean them, and actually put them back in the tubes and slide them back and forth, then remove them again and clean them a second time(that gunk is also on the inside of the tube), and then put them back in and hook them up. That took care of the problem.
