I was trying to fine tune my end carbs on my 6-pack carbs both mixture screws broke off 1/2 of the heads. Anyone have a good way of getting old mixture screws out? Or were I can buy new base plates? Or someone I can send these for repair ? I DONT WANT TO CHANGE TO PRO-MAX

My friend who's '71 v-code Challenger R/T I'm working on now sent his carbs off to Holley themselves to have totally restored.. Physically, they came out gorgeous.. We haven't gotten to the point of starting the motor for the 1st time yet..

Scott can probably help out too. He did the original Carter AVS 4618SA for my Daytona.

i had one taken out with an EDM machine before. the custom shop in bowling green ky can supply a plate and screws. if i remember correctly the 4bbl and 2bbl metering block mixture screws are the same thread but the taper is a little different.

Sheesh, no room to work in there either. One of Holleys not-so-great ideas.

Just a thought, but perhaps you could go to the dollar store and buy one of their small screwdrivers, cut the flat-end off and put a drop of JB Weld on it. Put it in there carefully, let it set up, and try twisting it out a few hours later. I'd think it would come out fairly easy.................

First thing you need to do before anything else is to get rid of the old cork seal,over the years it gets rock hard and you end up breaking off one side of the screw.Just about every set I get to restore has at least one broken screw.I have a pilot to center drill the screw and made an extractor to get them out,I have about a 98% success rate so far and I have done a "lot" over the past 30yrs.It's not easy but can be done.

Promax has the base plates reconditioned with new idle mixture screws installed for $75.00. Just ordered mine.
