The thing is, it wasnt doing this before I started messing with the intake and exhaust gasket replace. Well actually, it started going bad at the front, and was causing it to not idle. Fixed the gaskets, and then this started up. Is there any validity to the throttle shaft coming out of the carb casuing it to leak. When I bought the jeep, the vaccume advance wasnt hooked up at all and it was running fine. What do you think that could be from?

I asked u that earlier! Sounds like u created an air leak. Either u have something hooked up wrong or not plugged off. The only other senario is u didn't get a good seal when installing the intake gasket! As far as the throttle body leaking? I've rebuilt hundreds of holleys for race motors and never seen over 1 or 2 even questionable. Highly unlikely! Plug off ur brake booster and every thing else adnd see if it runs ok! I bet u have ur brake booster and ur pc system backwards

Delta, take a can of spray carb cleaner and spray all vacuum lines with engine idling. If the engine revs up you found your leak. Also spray the length of the intake manifold. Any time the engine idles up that will be a leak.

ummmmmmm no dont on that engine. trust me the exhaust header is right beneath the intake. you could burn your ride down that way. being a jeep mechanic for right at 7 years now i dont think your booster is the problem since everything was fine until you done this job. unhook the vacum advance and plug the line. make sure your booster line is hooked to the intake and booster, you should have a line that goes to your PCV valve on the valve cover hook it to the intake. plug the rest of them off and you should be set.

if not spray the gunk brand brake cleaner on the intake and carb area if you can tell it starts to run at a higher idle or misses you found your leak. by the way when you find it there is a very strong smell when this stuff goes through your engine, be outside and not in a shop when you do this.

torch wasnt callin you out on it, but brake clean isnt flammable enough to ignite on a header like carb spray.

any more questions just ask

oh yeah forgot, usually when a booster has a vacume leak you can hear a hissing noise coming from the firewall area inside the cab when the brake pedal is pressed.

other than that it should be good to go if all that is checking out.

the reason why i said leave the distributor vacume advance unhooked is because someone previously might have it advanced already and left it that way. or its muffed up and when you was slowing down the vacuem changes and the advance part didnt. you could verify this with a timing light.

All of my brake cleaner is non flammable. I have sprayed carb cleaner for years around intakes and have never had a fire. I know the intake and exhaust on this jeep is one piece. BTW I am an ASE certified parts specialist and and ASE certified Master Mechanic.

And I thank ya fer it...

I think i've got it going for now....from some research I've found that the stock carb is junk, and needs to be replaced with a 1 barrel webber/holley/and some people are saying an autocraft mc2100...my question is that if it came stock with a one barrel, will a 2 barrel fit my manifold?

Torch, what are the prices on some of these?
