I'd be obliged my friend, but don't get drenched on my account. Where in NC? Just want to know which of my family all across the state are whining right now.

I'm down around Charlotte....
Well this sucks... I just boxed up all my spare stuff and put things on shelves and I can't find the damn jets.  I'll find them once I remember what the hell I did with them. 
I did however find the receipt. I ordered 55 and 60 idles so that tells me they came with 52 and I ordered 140 and 145 mains which tells me they came with 135. I originally thought rich but I think they were actually lean out of the box, which may coincide with you stumble on accel. Also thinking about it more I think I ended up with a 55 idle and a 140 main. My air correction jets were 1.60 out of the box.
This is a little interesting since the idle seems a step up from what usually comes with them and the main a step down.

The 55 idle makes a little sense but the 127.5 mains seems a little on the lean side. I'd try bumping the mains up and see how it reacts. I'd also check and make sure the air jets are 1.60. Also when you say it does ok on hard accel, does it sputter at all when full throttle or is it smooth all the way after you get past that spot on accel?
The overall good news is that all the Weber 34ICT info you can get about jets on the web and here in the performance engine forum works for the EMPI's That's what I remember starting with when I did mine.
Also if you can get your hands on an A/F ratio meter it will tell you what the spot is on accel. I suspect it's a lean spot but that would tell you. You are more than welcome to come down here and use mine but it's a haul.  |

are these the 34s that CB sold for the bus that come with chokes? if so, there are a couple issues... the venturies are TOO small and the short linkage tends to have issues with binding if the plastic guide bits are cracked or missing.
contact me off list if these are the carbs and i'll tell you what i did to make them work well w/ the 'dreaded' 009.

Working backwards ... Thanks fye, but they are EMPIs.
Mx, I am quite familiar with the Queen City ... Go Panthers; my mom lives in Pineville. I'd taking you up on your help, but driving there appears to be the issue.
CB's jetting chart suggests the Weber 34s are 52.5/130 out of the box. I was a bit surprised to be told mine were 55/127.5 out of the box.
My VW guy has the car so I am limited as to what more I can tell you. It will be next week before we start playing around with the new jets. I'll post an update for those who come along behind me.

The EMPIs are very similar. Let me know.

the 34 ict I had once upon time did not have the balance tube and would not synch for crap either.
ditched them
Pierce manifolds I have used fo rjets and have found to be a pretty good supplier.
have dcnfs on my notchback and they were tricky to get set up but once they are dialed in sweet |
