I have a 350 0.040 trw flat top,186 casting 2.02 1.60 64cc,comp cams 280h hyd flat tappet,weiand stealth intake,600 cfm edelbrock 1405 orange step up springs,msd 8365 ready to run dist with blue springs and the 18 deg cent advance bushing.Its in a 68 4 spd camaro everything is fairly fresh comp test was 180 psi on all 8.The car runs pretty strong but I cant get it to idle for horse duckey at 18 deg initial and ported vacuum without the thing dieseling at shutdown.Coolant temp is 160 to 170 idle at 800 rpm to 900 rpm 8 in vacuum almost rock steady needle.I do get some response from the mixture screws and when I pull carb to check transfer slot it seems close to 0.020 but dont have measuring equip.Car likes to idle at 25 deg initial do i need to drill the throttle plates or further limit the cent advance somehow ....
thanks for your thoughts
