I have a 74 2l with dual weber 40 idf carbs. I took it upon myself to try and adjust them. I closed air bypass screws, turned the idle screw 1/2 turn in after initial contact, and backed out mixture screw one turn after lightly seating it. I also disconnected the linkage. I now can't get my car to start. What would be my next step? Thanks in advance.

I should run with your base settings. Maybe with the linkage disconnected you’re not able to actuate the accelerator pumps to get it started?? Below is a pdf file with pretty good instructions for tuning Weber’s.
