So many people too cool for school on this forum...I guess you all were just innately born with the knowledge you have...

Mr Chris,
Welcome to fixed gear riding, you're going to have a blast if you don't kill yourself. Tough to say what's going on without seeing what you're talking about. Some thoughts though:
1. Don't try to do a bunch of weird stuff to get it straight. It should work when everything is installed properly...and safely
2. Is the dropout bent? (apparently a typical problem with these frames)
3. Your BB may not be the right size
4. "When I screw on the fixed cog and lockring just enough for it to not risk popping off" Don't do this you're going to kill yourself
5. If it's not too late, think about returning frame and spending a few more dollars on a kilo frameset you won't regret it (amazon has pretty liberal return policies)
6. Just take it to a bike shop
