Backfiring help!!!

Ok so I purchased a motor from a guy and had it installed a few days ago. Well it fires up perfect but during idle it sounds like its backfiring. It's coming out of the driver side exhaust so I unplugged the spark plug wires one by one and narrowed it to the #7 plug. The motor appeared to be clean when purchased and it sounds great but that backfire sound is killing me. Where and how should I start to resolve the issue?
