For a baseline I run 52 jets, a 32 squirter and 6.5 power valve on my 390 CFM Holley. Timing at 10-12 degrees advanced. Idle screws: start at 2.5 turns out. Mine is a tad rich but not enough to foul plugs. Plugs read good with this setup.
start with the electric choke vertical and adjust from there. Probably going to be a bit rich when cold. I like to keep it just loose enough to turn it with effort until I get it locked in.
Vac advance is on the lower port on the carb, trans on upper.
Mine is a tad rich but not too bad.
Runs really smooth! Hows the 200r4?
