Bolt reset problem

[zorrotmm]

My setup is a ULE left feed, xvalve, LVLX and ULT. I've had a reocurring problem with the bolt not quite fully resetting. The gun just doesn't shoot unless I push on the bolt with enough pressure to make it reset. Usually this happens, I mess around with LVLX carriers until it works again, but eventually it happens again. Is there a specific fix or area to look at for this problem?

Also having this problem, but on a 1 month-old Pro/Classic. Any ideas on how to fix it?

Marker fires fine with gas only, but when running paint it sometimes gets stuck 1/8" from fully cocked. What gives? Kinda gets annoying getting your bolt stuck every 2nd shot during a game...

Add shims to the Level 10 one at a time until this issue stops. :D

Awesome. I had a feeling I needed to go to the shims. But then there was the inevitable question: Do I add, or take away? Screw it, ask AO. Thanks rogue.

Actually, while I've got the thread going, what's a typical symptom of too many shims?

A symptom of to many shims usually means a steady leak down the barrel in all me experiences.
