find an Edebrock carb, pit it on, and go. I fought a q jet for about a week, bought an Edelbrock at Autozone, did the pre adustments according to the book that came with it, and havent regreted a single moment of it. Well worth the money.

tightened down the area that was leaking more than the rest of the bolts and so if it is leaking then I'm just going to set the dang truck on fire cause it's pissing me off,

 Sounds like the base plate is warped.

Mud, I would like you to explain this in a little more detail if you would

okay, what I did was take some carb & choke claener and spray around the base plates to try and find a vacuum leak, found a small one at the back left corner, so I went and got those really thick gaskets that they make and put those in there and as I installed the carb, I tightened it down in a criss-cross patternt but tightened that back left corner down more than the rest, that worked but only slightly. Proceeded to check for leaks again, and found none. It was still running like crap though, so I pulled the carb back off, and put the old one back on (minus all the emissions crap though). The truck actually seems to run better now, probably becuase there is no excess emissions stuff on there now. So, what I have determined is that the carb was bad, and probably need to be rebuilt.

I think everyone here thought it was new. You could have so many problems with it that it would be impossible to diagnose it on a forum. If you buy a brand new Holley and put it on making sure you have no vacuum leaks it will run right out of the box. You will have minor adjustments as no carb can work on every possible vehicle with just one adjustment. I'd put the old one back on and wait till it is actually a problem before replacing it. Seriously if you have the stock intake on then you don't need a high performance carb. I get the feeling you want to make a few extra horsepower but aren't ready to go full tilt. If that is the case address your ignition system first and then next would be a dual exhaust. For the ignition get a good coil, module, curve kit, adjustable vacuum canister, wires, cap, rotor and plugs. Get it all adjusted to what is right for your vehicle by playing with the timing of the mechanical and vacuum advances as well as initial timing which is where you have your distributor set to. You are goin to need a timing light so you can actually keep track of what is going on too.
