I have a problem with my 34 and need some help. Fired it last month at Knob Creek and it ran great. New barrel, bolt, recoil cone,spring is correct length. Took it out last weekend and all it would do is snap on the round, dent the primer but not enough to fire. Changed belt and ammno still same results. Wonder if during cleaning after firing moved or changed something in trigger assembly. Any advise appreciated. Steve
