White smoke mist around Carb.
Am having problem. I had eliminated the rats nest only to simplify things a little more, Accidently it eliminated a bad vaccum leak that it already had. Ran perfect one day, after that it wouldnt idle good it really wouldnt want to hold idle I had the hood opened when trying to keep it going to see if I saw any leak, but instead I found a mist of water around the carb on the driver side and vapor as if it was steaming out of there, I know its radiator fluid due to the smell of it and the exhaust white smoke. Also eliminated emmisions along with the rats nest and shutter valve. Anyone has any suggestions on what mine might be doing? I've owned the car for 6 yrs and havent put 50 miles on it LOL, Help!!! Thanks.

I agree that it might have sat for too long. That could mess up the engine pretty bad, as well as the carb of course.
There are a few places that coolant runs near the carb. Make sure you didn't bump anything loose. That is always possible.

Get a new intake manifold gasket, plus the two O-rings that go along with it. If you still have coolant going out the exhaust after that is done, then read this thread: https://www.rx7club.com/1st-gen-archive-71/engine-coolant-seal-repair-maybe-750774/
Good luck.

^ Intake manifold gasket. At least I hope that's what you meant to say. If your O-rings are toast you can always just plug the two coolant ports with 20mm freeze plugs. You can get them at pretty much any parts store, but if the idiot behind the counter says they don't carry them, then he isn't looking hard. Use some JB weld to hold them in place.

Thanks Chris, I fixed it.
Also, when installing the freeze plugs you don't need any J.B. Weld or anything like that. They are a very tight fit, and pressed in. They are a very soft metal, so they deform to match the size/shape of the opening. You just have to be careful when pressing them in, so that you get them to go in straight. I used a tight fitting socket (one that just fits inside the plug) and put an extension on that, which worked great as a press tool. Actually a very easy modification to make to your car.

Thanks man!
And, when I installed the freeze plugs, it was pretty clear that they would provide good sealing. I did not see a need for any kind of sealant to go with them, so I didn't use any in order to avoid future issues with removing the manifold gasket should I ever need to again.
Just be careful when installing them, so you can make sure that they go in straight. And since they're dirt cheap, you might even want to get a spare or two just in case you screw up on the installation.

Pull off the spacer and make sure all surfaces (manifold, spacer both side, bottom of carb throttle body) are smooth and flat. Do that before you go putting any sealant all over it. Keep in mind if you have to pull the carb or spacer off you'll have to put new sealant on, which means you'll have to clean off all the old sealant. This could be quite a pain in the ***.

My black spacer between the carb and intake didnt have seperate gasket when pulled it out. is it suppose to? or would I be safe to put sealant on it? What would be the best and safest route to take guys? Thanks for all your replies they all have been very helpful THANKS...

The rubberized gaskets (they're actually pretty stiff, but they do flex when the carb is torqued down) are permanently bonded on, and you shouldn't see a separate gasket, no.
Times past, I've used a really thin layer of blue silicone when I suspected vacuum leaks. It's fairly easy to rub off without tools, later. It needs to be really thin, though, as you don't want to block any of the small vacuum ports.
