Ok a little update.... Thought I'd share my results for reference?
I have dropped down 2 jet sizes on the primary side, installed the 2.5 power valve and drilled the 4 idle circuit air bleeds from .073" up to .078" This improved the A/F ratio on the gauge from 10.2 to 12.5 or so, and gave me some adjustability on the idle screws. I then tried drilling two more to .086 and installed them in the primary side. This made no difference in adjustability or on the A/F gauge. Just for kicks I tried removing one air bleed on the primary side while the engine was running and again it made no difference? So that tells me I've maxed out on the air bleeds?
Vac at 900RPM's is 6.5, in park 4.5 in gear drops about 200RPM's to 700 or so
What to do next?
Jet down further on the primary side?
Jet down on the secondary side?
Drill 1/8" holes on the primary butterflies? ( no holes now?)
I never did hear back from Quick fuel reguarding those missing? brass inserts in the metering block? I'll have to phone them this week?
Also it's crappy and rainy here so I can't take her for a rip to see what happens when the 4bbls open up?
