New to the board, checked out the stickies and relevant posts from the past but still not able to diagnose problem.
A year or more back I bought a used TNW SA MG34 on Gunbroker. Nice, good price, the guy indicated it worked well. When it arrived it was selectively gooped with what looked like a white, lithium based automotive grease and clearly hand been in place for a while and it had not been fired in some time. I cleaned it and put it away to get out this spring and try to shoot.
First problem was a mainspring that was so weak it wouldn't strip ctgs from the belt. Corrected with new spring, that issue isn't a problem.
The problem I'm having is that I can't get a ctg to feed initially by pulling back on the charging handle. The case passes through what I'll call the feed try (don't have the terminology down) but gets bound at the 12 o'clock position on the bolt locking cam/receiver roof. When I open the cover I'm looking at the case head tightly up beneath the feed try held in place by what I'm assuming is the extractor.
I don't see any wear on any of the feed parts, the blue or plum is pristine. So that's telling me it hasn't been used much if at all and doesn't have a history of binding which either could be the ammo being finicky, or the seller might have been somewhat less than honest with me and it's just never been fired because it's not functioning.
Since this firearm is new to me, I honestly don't know if it's every functioned properly, and the issue didn't seem to be addressed here in previous failure to feed posts. I'm using Turkish ammo from 49 which fires very nicely when loaded one at a time dropping them into the breach and allowing the bolt to slam home. I've got a very expensive single shot at the moment.
Any advise would be appreciated. Thanks.
