Well I went ahead and removed the rats neat from my 83' and now I have a few problems.

1. The blue cover for the carb has 2 holes that were not supposed to be covered, but what goes in them??

2. the engine is misfiring and wont hold idle it sounds like a pig trying to stay affloat at 1,300RPM

3. Had to drive it home from where I was taking the nest out and it was fine for a bit and then it just felt like there was power on and off and the car was shaking and hessitating to move but when you give it more gas it would smooth out...

what should I do I was thinking of going over all the hoses that I plugged today and over the plate that I made for the intake manifold after taking out the ACV i think it was called, but there was also an elbow that I took out and under it there is a little hole does that get coverered too? also It might just be a very poorly set carb and maybe I have to advance my timing on the dizzy but thats all the ideas that I have of where I fucked upp if you have any suggestions please let me know, I used the Rats nest removal .PDF that is floating around here


thanks

that elbow has to be blocked off.

 

What did you use to block it off? its only a small hole but is that where that sound is comming from??

thanks

i took off the elbow

crushed the end in a vice, and folded it over.

then crushed it again and folded it over.

then i put it back on....

Yhe I was thinking of doing that but taking off the end tube and just keeping the bracket that bolts on then wealding it shut just so it looks better. I found out what that sound was it was my fabricated plate not sealing the hole, now I have to put the elbow in and see my exhaust cause its farting infront of the cat, which im taking off as soon as I can save up for a pre silancer..
thanks for the feedback keep em coming I will post pics of my engine today

Wanted to chime in since this thread is open.... do you need the shutter valve? I capped the big hose and small hose after removing the nest.

 

also, where to hook up the vacuum.... If I remember correctly, the big tube connects to the air filter.

 

ahhh so the big one goes in there, the one going from under the car?
also I just plugged the hole where the elbow was and now my car is just not ideling it just starts up with my foot on the gas revvs upp to what ever and then goes down slowly and dies. Is that just the carb and timing issue or something more??? let me know thanks

the only one going under your car I can think of would be the air hose going to your cat. you just plug that one or weld it shut (on the cat). The big tube I was talking about is the one on the shutter valve.

 

Ok here are some pictures of the rats nest removal can you guys look and tell me if I did it right,

also there is a picture with 2 hoses plugged and one of them has to plug into the air box which one?

if i did something wrong let me know I need to fixxxxxxxx, lol...

But so far its working out good just doesnt IDLE but thats the carb and timing I presume

 

it looks good to me. just start the car and spray carb cleaner around all the vacuum lines you capped and spray around your blockoff plates too. if your idle goes up that means whatever you just sprayed is sucking the fluid in.

 

Thank you for all your input youve been great help, next project..... E-FAN!!!! thats next weekend and i already have a RB race Header and that will be going on when I get some pieces from RB

again thanks for the help I will try this tommorow morning because I am at work till 9 pm and people in my neighborhood hate me for trying to fix my car all the time ... Good old loud MAZDA

Im going to do this tomorrow https://www.rx7club.com/1st-generation-specific-1979-1985-18/shutter-valve-488690/

 

If you just removed the rats nest, and is not idling now, but was before you removed it, you can bet is a VACUUM LEAK. Find it. Kill it. Your problem will vanish.

 

I had a cap big enough to fit over the end of the elbow.

 

Ok ive found the problem when I was bolocking off the 2 tubes the one leading below the carb pushed out so now Im IDLEING, a little rough but I will adjust the carb lated had to come to work, next thing im going to do is take off the butterfly Valve. Thanks for all your support with this.

one more thing the air box now has 2 openings one on the pasanger side and one right behind the opening of the air box are these supposed to stay open? or do i close them off?

Now I can install my RB race header YAYEEEEEEEE
