Thanks Chev. I have removed the plunger retaining bolt. The spring and plunger do not move or come out with the bolt out. I've sprayed it down with wd40, but that didn't do anything. Could the plunger and spring be too low? If the spring/plunger are supposed to come out with the bolt removed, I guess I need to get out a prybar. The manual does not discuss removing these.
