notch8,
You now have access to the parts list and manuals area. In the near future access will be automatic once a donation is received but this could be still a few months away yet as we are waiting for the new update for the forum to be approved.
As to the Victa Rapier carby issue you might have cracked the stem that the screw goes into. The way to check it is to remove the primer cap and check for hair line crack. The needle does not have a spring as it should move freely.
Hope that this is of some help.
