Constant Force Spring that keeps pressure on the nails was broken
This is the first time repairing this tool, and I removed more parts than necessary.
In order to replace the Constant Force Spring, I had to remove the nailer magazine from the nailer body. This task was not difficult. I used a socket wrench and an alex wrench to remove the screws. Once the magazine was out, I made a mistake removing the part in back of the magazine that holds the spring while you load the nails. That was not necessary because the Force Spring and housing comes out of the front of the magazine. It was very easy to replace it with the new spring.

With a little effort it worked
The part I really needed isn't made anymore, so I figured I would try this one, it was close enough. This worked with a little effort, I had to pull and pry the button through the end of the magazine until it caught. I accidentally bent the spring and now there is a slight hesitation, but nothing I can't work with. The nail gun is 23 years old, so a slight hesitation is to be expected. Would recommend and buy from ereplacementparts.com again.
