Re: 2.8 carb question
If you really wanna clean our the carb run sea foam through your gas tank. Its only $8 at walmart and I pulled my carb after I ran it through and all the carbon buildup in the bottom of the manafold was cleaned out and the carb looked perty good. I just did a full tune up and exhaust on mine and I can barely chirp the tires on takeoff so don't feel to bad there, just work on the suspension and outrun them on the corners.

Re: 2.8 carb question
a 4 barrel qj is mechanical secondary, it would flood the hell out of a 2.8 an aftermarket carb with vacuum secondaries would be better.
i have a good running fuel injected 2.8 and it wont chirp the tires at all. its a v6.

Re: 2.8 carb question
something's wrong with your cars guys, I can spin a little in second. first is no problem. do the seafoam stuff, it can really work wonders.

Re: 2.8 carb question
yea, tires do make a big difference. I've got 235s on mine, but they're not super sticky.

Re: 2.8 carb question
Ok if it is the carb I think it is then its complete crap for any form of performance. I would save some cash for a cam and the 4bbl set up and then do exhaust and you should have some chirp.

Re: 2.8 carb question
I like my '84 Camaro, but the factory 2bbl 2.8 is a dog, plain and simple. On my '83 Camaro, I used to "cheat" by holding the choke all the way off with a rubber band ("backyard" though it may be), and that helped some, but not much. My '84 is better (with a properly working choke), but still won't spin the tires much. These engines are only rated at 107-110 HP; and often don't even feel like they're performing up to that standard.
There is a holley 4bbl out there that will sit on an Edelbrock intake made for the 60° V6. My younger brother worked with a kid that had this setup in his '84 Camaro V6, and the kid said it worked great. I priced it out and it came to around $900 for the parts. But other than that, there's really nothing you can do to get more power out of this motor without internal engine work.
My advice to you, if you're going to keep that engine, is to keep an eye on the carburetor float, check your oil once in a while , and don't beat on it much. A big problem with these carb'd 2.8's is that the carb float will sink and cause raw fuel to dump into the crankcase and thin out the motor oil. With an already-weak crank, this sets the stage for spinning a rod bearing. It happened to my buddy's car, and then it happened to mine too (and with 138k mi, I was trying to baby it).
