Need some help.....swapped cams

MoparMagic0069 said

I know everyone has there opinions on the 284/484 Purple Shaft camslook like the original style carbs, well the air/fuel mixture screw on the drivers side does absolutely nothing....and the idle screw is so touchy! You barley turn it and the idle runs clear up to 1200, you barley move it the other direction and it falls and than shuts off. Any suggestions?....

OOps, I missed the part about only one side not working. If one side does work, then The T-port sync may not be that far off.
So then you may have multiple problems.
Or it may just be a problem on the bad side of the carb. It sounds like the low-speed circuit on that side has gone AWOL. It may be that there is no vacuum problem at all. It sortof appears that the main on that side is working, cuz you did not mention an issue during the break-in. So I'm gonna guess that the problem is restricted to that one circuit.
Unless the valve lash is too tight...
