Hi All!
I have a fairly rich idle mix (black dry sooty plugs). The plug tips are tan to lean looking after running at speed. The car drives out great. I've:
Compression checked (warm,WOT): 155#, 160#,160#, 155#
replaced (TRF): pertronix electronic ignition (was running points), rotor, cap, wires, plugs (L87YC), and coil (FLAME THROWER)
verified static ignition timing: 4 BTDC
verified valve adjustments
VERIFIED THE ~.73" float adjustment for BOTH floats of each carburetor.
Verified good engine ground
I run 93 octane 100% Exxon
What have I missed? How big of an adjustment can I make to the floats (.73"+?) to lean the mix without starving the car at speed?
TIA!
