just swapped intakes (torker 340 to a Edelbrock Air Gap) and I am trying to calibrate the carb (edelbrock 1806 Thunder series AVS).
I richened up the carb a bit because I thought it might have been running a little on the lean side, now it won't idle below 1000 rpm (at highest vacuum reading of 20").
The idle set screw is all the way out and it idles smoothest with the idle mixture screws turned out to about 3.5 full turns. My gut says this is too much
Is this a sign of being too rich?
I also noticed that when the idle set screw is fully turned out, the throttle arm doesn't hit the metal stop, is this correct?
Specs:
1974 360
solid lifter cam (specs unknown) 20" vacuum at idle
1806 Thunder series AVS
Air Gap intake
18 degrees initial - 36 total, all in by 2500rpm
