Panic,

'way too much' means too soon and too long, basically when it it is unneeded.

I don't know exactly what 'PVCR' refers to.
The power valve feed holes for the front and rear are 'stock'.
The needle and seat for front and rear are .100
The accelerator pump is .30 cc
The shooter size is 25
The front jet size is a 59 (stock is listed as 51)
The rear jet size is 'Plate #31 stock'

All the other settings are listed as stock. My carb guy said to make sure to save the sheet for future mods to the carb.

If it isn't obvious yet, I'm no carb tuning specialist. I've never had a Holley until my carb guy built this one for me.
But, correct me if I'm wrong, currently my mileage is not as good as it could be due to the power valve opening under light acceleration, right? And, most likely the #59 jet is not the 'perfect' jet for mileage for my engine, but based on the performance I don't think that it is way off, do you think?

Previously I changed the spring for the vac secondary to get the secondaries to come in later. I did this because I thought they were coming in too soon casuing a light throttle response (bogging) problem. After the going to the second stiffest spring possible the bogging problem did improve dramatically. But was planning on having to change it again after I get the power valve situaton under control.

All advice always appreciated.
