I don't think the Romanian AKs are low quality, the finish typically isn't that good, but other than that they're usually just as good as any AK.
I's been my expreience that the WASRs have more problems, but they're caused by the Trained Monkeys at Century not the Romanian manufacturer. The problems I've seen in the small sample of WASRs I have experience with have mostly had to do with the magazine well.
The Monkeys filed down the mag catch on my WASR-3 too much in an attempt to get their butchered converted 5.45 bakelite mag to work with it. When I tried to use proper mags in my WASR-3, they wouldn't work because they would rock too far back and cause the stripped round to fail to enter the chamber and get smashed by the bolt. The proper fix would have been to simply replace the mag catch, but at the time K-var was sold out of the pivot pin I would have needed, so I opted to weld up the catch and file to shape. It works great now.
The other experience I had was with a friend's WASR-10 being very finicky about feeding certain types of ammo. It wouldn't feed Wolf HP at all and was picky even with FMJ. I found that the rear magwell had been improperly bent inward rather than filing the mag catch slightly. This resulted in the magazine presenting rounds to the feed ramps too low causing them to jam into the breach face. Simply fix was to bend the receiver back to proper proportion and then file the mag catch until a magazine would lock in and release without too much force.
Here are three basic things that you can check:
Rack the bolt. It should move forward and backward and only "catch" in the middle of travel i.e. about half way back. The "catching" here is normal, it's just the bolt rubbing over the hammer. The travel of the bolt should not be stiff or feel like it is dragging anywhere else.
Check to make sure the Front sight is relatively straight up and down. It's normal to be a little canted to one side or the other. This is usually just a cosmetic issue- rarely is a front sight so canted that the rifle can't be zeroed.
If you can, insert a magazine loaded with a snap cap, or other dummy round, pull back the bolt handle all the way, and let it fly forward. The dummy round or snapcap should then be in the chamber and the bolt should be all the way closed. When you pull the bolt back again, the dummy or snapcap should be ejected.
If the rifle passes these three tests, you should be fine.
