Oh, and there were two other steps. The third is to then adjust the 1/8" hex screw in the solenoid to 425 rpm. Then finally to bend the fast cam idle follower to get it on the high point of the cam at 2000 rpm, and then reconnect the EGR and Evap hoses. There are no instructions on the idle mixture knob, but my old Chilton's guide says to tighten it until seated and then back it off two turns.
