Idle on startup can be pretty choppy if the engine is cold, but it should not take long to hold it's own idle. FWIW, my Warlock will idles around 600rpm in gear when warm, there's no reason for it to be >1,000rpm. I would target no more than 750rpm on the throttle stop [assuming you don't have a fast-idle w/o a choke]
When the engine is warm, the idle is at about 800 RPM. My question was on a cold start up as my car idles down low. Every other car I have starts idle >1000 RPM and drops as it gets warmer. I'll have to see if I have the fast idle screw on the passenger side of the carb. Hopefully this weekend.
