i was told to make sure im on the idle curcit when i adjust my carb how can i tell is there a certain rpm

There are two idle mixture screws on your carb. ( On the front of the carb, not the screw on the linkage arm that sets your idle speed) Turning them in leans out the mixture, and out makes it richer. If your car (all warmed up) is at idle, and you turn either one or both screws in, and it stalls out, then you're on the idle circuit. If the screws have no affect on the idle, then you're not idling on the idle circuit. If that's the case, get back in here and let us know what's happening.

no it stalls out and then i adjusted them with a vacuum gauge again

Then you're on the idle circuit. Do you adjust for max. vacuum by going back and forth between the two screws? That's basically how it's done. Are you having a problem in particular, or just wondering? John

no problem, just in stalled a bigger cam and wanted to make sure i was getting the max idle mixture adjustment. after i get the highest reading on the vac. gauge then i turn them a quarter back

I would say no on the highest vaccum method. If you used the lean drop method: you adjust for highest idle speed than drop 20 rpm on each screw. The screws do not need to be the same in or out.
