Rich idle, would this help?

Subscribed :I don't have a Vac setup to test that way yet , I will by the end of the weekend however because I have been chasing my tail with this very problem , backed the car out of the garage and it flooded itself out , we setup the carb , ended up 1 turn on the mixture screws and got the butterflies closed and the idle sort of stable at 700 rpm , car would idle down at the light and start to stumble if kept in gear , would not cruise at 1200-1600 rpm had to be either on the gas or off , diagnosis vac problem probably blown power valve , fast kit and reduced from 6.5 to 3.5 , retorqued intake , car runs , cruises at low rpm but accelerates much slower , diagnosis to small a power valve doh , still had a knock inside , replaced perma torque intake gaskets with proper gaskets for RPM , no more knocks or ticks , car starts a little better plugs are cleaner but haven't had a chance to really drive her yet since she is now low on fuel from tuning and won't make it to the nearest station that sells ethanol free 94 , tomorrow is test run day and I expect the plugs will stay good , but I will need that vac gauge setup to get the right power valve , my first recommendation to the OP would be re-torque your intake and if you are running those blue felpro gaskets with a non stock intake then get rid of them .
