I just finished my installing a Holley carb in my 12a rx7. I have a problem with it trying to hold idle could the problem be a vacuum line I didn't connect or something ? Fuel pressure is set at 5 psi and everything is brand new plugs, carb, intake, exhaust manifold, fuel pump, new fluids and oil.

 

i just did a 6 port motor with a custom intake and a 500 edelbrock carb. it was a mess to start, get to idel, and run very well until i did some decent idle tuning on it, as well as proper jetting and so on. i have a wideband o2 sensor so that makes tuning it very easy to read. no carb is ever going to bolt on and be good to go. its going to require so tuning even to idle nicely... as i found out over a week of testing and tuning.

 

Thanks turbo for the reply I will be attempting to fine tune and get it to run decent
