And power valves do NOT come in any kits that i know of. Except in OLD Sorensen kits. Stock PV's usually are too big running a 2x2. most run #67-#68 in them. Your running too much gas through them your over carbed. OMO ken ct.

I found .043 in front carb and replaced with .045 to match rear...appears .043 is a better choice (your recommendation) in all 4 locations. H&H recommended these jets and you are correct I bought #65 PVs separately (and emulsion tubes) as well as recommended by others. (Appears #65=.035dia, #66=.033,#67=.032, #68=.031, #69=.0292) Never had the pedal to the floor to get into this circuit as a bit rough prior to that as I described.

Think about it, the gas from 2 accelerator pumps when the engine originally only had pone. Too much!

How about changing the accelerator pump rod to summer from winter setting on the 97?
My setup has been in place since my Father owned the car in the 50's. No pump mods I am aware of and never ran a regulator- pump output is approx 5.5psi. The Internet has allowed me to make the regulator and jet "improvements".
