bolt stick

[vintage]

retro valve, level 7, new spring, on off assembly looks good, where else do i look?

Been a while since I worked on a Level 7.

1. Oil everything.

2. Is it not firing at all? If it's not firing, then turn the velocity up. If it's firing intermittently, what velocity are you at?

3. Do you have a spacer kit? If so, try a longer one.

4. When is the last time you did a complete seal overhaul? Even though things look good, sometimes it's just easier to do an overhaul.

If you are getting bolt stick with a level 7 bolt and a new bolt spring, it is usually a powertube spacer that is too short. Install a longer one.
