Next, adjust the idle screws as mentioned above by flyingtim but look for the highest vacuum on each one.

I just picked up a vac tester today, and a flair nut wrench set so I don't strip the bolt when I take the fuel line off next time. How do you tell which is ported vacuum and which isn't? You're talking about adjusting the two mixture screws in front right?

Aside from really wanting a 4bbl setup, the 2bbl setup had other problems of it's own.

I'd grab the carb with the electric choke. It's what I have on mine, and in my estimation, its just a simpler setup. No linkage to bend/adjust, don't have to worry about the choke stove getting gummed up when your inner intake bolts start to seep oil, and they're easier to adjust when the weather changes. Just loosen the screws holding it on and rotate. Just need to run a key on 12V wire. And if you want to be really trick, there was a member who remarked that he wired his choke in through his oil pressure wire, so it only got 12V when the engine was running, not just when the key was on (so you don't have to remember to make sure your key is in the OFF position when you don't want the choke to heat up).
BHyatt, the original setup that worked well was a 2 barrel, which for obvious reasons isn't acceptable...  |
Yes I'm planning on putting the rebuilt Qjet with the electric choke on. I've already got the wire set up for the choke. In the mean time before I get the new carb, I am going to do some more tests on this carb because I'm curious about what's causing this problem. That and it wouldn't hurt to test my fuel pressure anyway.
I agree about the 2bbl being unacceptable.
