Now time it, then once its timed plug back the switch and from there shut off engine and then start it again, now ur car should run fine and dandy

Is that for base timing only or timing period? isn't there also a procedure for timing at 2000+ RPM?

I'm 3 states away from my FSM, so can't help with the idle @ 2k question. Yes that is for setting base timing. Take it to 6⁰, then if it runs right you can try adding some to it. Some like 8, a few like 10
