Mcwoodduck,
make sure the bolt is clean and dry. No gooey lubes etc. No springs in there. The romanian uses the firing pin as the ejector, and when they get gunky the pin does not slide back into it's slot so easy and will jam up when you try to chamber the next round. Clean the bolt and make sure the firing pin moves very freely in the slot and it might help. Also look at the feed lips of the magazine. They do tend to be a little beat up.
good luck
