my TII BAC doesnt have a screw...
i got an fc3s.org jspec and i am finally tracking down an idle problem after getting the whole car put together. the only problem is that the BAC doesnt have an adjust screw on it... how am i supposed to adjust my idle and get it to smooth out? i heard the JSPEC BAC's didnt have adjust screws... how did the japs adjust their idle?

i just did the throttle body mod, cleaned out the runners/butterflies, took off TPS and reinstalled it, made sure there were no vacuum leaks, etc. and i realized my BAC doesnt have a screw in it so i really dont know how to adjust my idle other than timing (its about -5 retard) and idle stop screw... what do i do about my idle?

And don't let anyone tell you that you need to remove the TMIC to adjust your Idle via the Throttle stop screw!
