Edelbrock AVS fuel pressure / Carter M6866 7.5 psi pump
Post #13 nailed it.
The fuel inlet of Carter & Edel carbs are IDENTICAL. Same n/seat, same float [ although Carter did use different shaped floats in some models ]. The parts can be swapped between brands. Here is the chart AGAIN. If you have 7 psi, that is FINE, & I would reset the floats to 1/2".
You maybe mistaking cruise mode for idle mode [ running rich ]. Depending on a variety of factors, the idle cct provides fuel up to about 60 mph. So changing jets & rods will do NOTHING.
[1] idle vacuum?
[2] idle rpm & timing at idle
[3] how much transfer slot is showing the blades at idle
[4] does removing & plugging the PCV change anything
[5] how rough is the idle
