I posted this on classicbroncos as well, thought I'd try here for some location specific advice.
I've had a miserable time trying to get my reman 2100 tuned the past few years and have just dealt with it; terrible gas mileage (~8) and just never seemed right. Sadly I've been away from the bronco for a while now and when I went to start her up yesterday, I noticed only one venturi was getting gas and the accelerator pump was leaking. This prompted me to do a rebuild, which I would have done on my original carb, but it was missing all of the choke components.
One jet was all banged up when I got to it and nearly impossible to get out. The other is in good condition and is a 45, I assume they both are but you never know with remans. Also, not sure if it matters but the mixture screws are different from each other. I did get a ton of crude out of it.
Could this be at least part of my problems with the tune? What size jets should I get, 48's? She's a stock 302 except an HEI ignition and long tube headers. Lives in CO at about 6,000ft. The best I can tell the venturis are 1.08, but that's just going off the stamp on the side of the housing. I couldn’t find anything about the markings on the venturis themselves, maybe one of you gurus can help decipher them.
