what do you mean by sucked up? Is your chain skipping on the sprocket?
If i'm picturing it right, it sounds like you have quite a few extra links in your chain. This is probably limiting the amount of teeth on your rear sprocket that are actually engaged in your chain, causing it to skip. Take some links out and see how it goes.
Post a picture of your setup if this wasnt the problem.
