Still super tuning this Quickfuel.

I did drive it a good bit, and the idle and low speed AFR is all over the place
The heavy primary and near WOT goes to 11.5 and then drops back to 13.1 AFR.
Cracking just into the secondaries shows a 14.7 lean spot, secondary shooter is .031 and adjusted correctly. Increasing PVCR from .054 to .059 didn't move the WOT AFR, still stuck at 13.1.

I've just relocated the primary IFRs from the high to low position.
I've also blocked emulsion holes 2 and 4 in the primary block. This should mimic the classic holley metering block setup.

I haven't road tested this tune yet. Before I do more road tuning, do those modifications need to be done to just the primary block or the secondary as well?

Current tune:
Primary
Proform metering block with (4) .028 emulsions
.066 LSABs
.030" primary IFR, low position
.032 HSABs
71 main jets
.059 PVCR
7.5 power valve
2 and 4 emulsions blocked

Secondary:
Proform 4 emulsion block (4) .028 emulsions
.066 LSAB
.032 HSAB
80 main jets
.031 IFR, upper position
all 4 emulsions open

Fuel level halfway up the glass front and back. Currently idles at 13.5AFR with 13" of vacuum at 800 RPM.
