ok thanks so what i have to do is screw in the idle speed adjusting screw(to get low idle) and also screw in the idle mixture adjusting screw(to have air balanced between the carbs), balance the carbs using there idle screws and she be done. i hope it doesnt play havoc with the anti dieseling solenoid

i have a L18 datsun 720 ute with twin flat top su carbs(Hitachi) but i cannot get the idle low+balanced yet everything is loose(undone) 1 su is very unbalanced i have found how ever there are 2 other screws that no body mentions at all these are outlined in yellow in this pic i have added (note)not of my ute but exactly the same as what i have the carbs are from a 180b sss from what i have been told) Yes i have a carb balancer and all the stuff needed also they do not leak any air fuel(only brake booster leaks air but i have blocked the very tiny leak off) does anybody know what these are set to or how to set them??? any info is much appreciated
