I still haven't turned screw 2f back in a quarter turn yet, so it does idle a bit high when warm. All plugs are within normal resistance, and receive the correct amount of voltage as well. Still need to perform a compression test to rule out variance between cyls, and I do have the dreaded 603 head cracks to contend with at some point. I haven't put the washer reservoir back in since beginning this project, but it sits in the stock location.
