It might take a while for you to get a response, this is the first time ive seen a question about aircon.
This is probably very little help but ive got mine idling at 600 rpm at 20 degrees base timing (vacuum advance unplugged) which goes up to about 30 degrees at idle with vacuum plugged in (4K-U engine with dished pistons, no air conditioning). Most people struggle with 600 rpm with the stock 4k carb from what ive heard.

with 4K because its carby and has a manual choke, you won't really have much of a "normal" RPM depending on full choke/half choke/ open, also temp

but mine can idle from 200-1000 rpm depending on choke openness
