Hey guys, I seem to have a compound problem involving my Level 10 and actual firing

With my old (kinda rusty) gold bolt spring in there seems to be bolt stick, with the system not resetting after I shoot it. I added 2 shims and that fixed it a bit, but it still doesn't fully reset sometimes....so I replaced the old spring with a new Red spring....which brings us to the next part

With the red spring in it doesn't shoot. At all. I can feel pressure in my trigger pull, but nothing happens. Also, the red spring is about a coil and ahalf longer than my old bolt.

I don't think it's the carrier, but suggestions are welcome. Please help me.
