Please help!

Hey guys,
I recently purchased a 1970 c10. It's mostly original besides the bad paint job it got a few years back with an original 350. It did not run well when I purchased it but it would crank up and attempt to. I put a newly rebuilt rochester quadrajet on hoping it would solve the problem but it didn't. It will now start up and idle for about 30 seconds before dieing out. If I give it any throttle at all it will bog down and basically suffocate itself. Any ideas what the problem could be? I was thinking a vacuum leak but everything there seems to be fine unless I am missing something. It is also relatively low on fuel (about 1/4 tank) and I noticed that the new fuel filter I put on when installing the new carb already has some junk in it so it could be bad gas but I'm not sure if it would make it completely die out or not. I am no mechanic but I am learning. Any help would be greatly appreciated. It's driving me nuts!

Regards,

Tyler
