Rough running 318

So i tried richening up the mixture screws and idled it down to 900. It runs and doesnt act like it wants to die. Before i made it richer, i used the manual choke to see if it was running lean, and choke off the air just made it want to stall out. I drove it around after I got the idle stable, and its alot better. Now it pops out the exhuast right before it shifts. Other than that it sounds like its running on all cylinders, and i sprayed a little bit of water on each header tube to make sure it boiled off. The cap and rotor are really clean. I also found a spark plug boot that was torn on the dis cap.

The carb is a 1406 650 cfm with a manual choke, and I blocked off the little vacuum port hole where the electric choke was. I blew threw the fuel filter and it didn't have any restrictions.
