i see many car same model engine normal 1 rpm turing on or off air-con it will be same rpm 1.
Thanks again
I am not sure if I understand your question correctly;
I think you are asking if you adjust the idle to high rpm (1.5k)
the rpm will drop to 1k when air cond is ON, and then it will
go back to 1.5k when OFF?
1) There are separate screws for air-cond ON and air cond OFF
(located on the left side i.e. passenger side) of the carburettor. So
if the vacuum actuator (UFO) is working you can adjust it to
automatically "press the pedal" when air-cond is ON, and let go
when OFF.
2) When it lets go, a different screw takes control of the idle rpm.
3) You have to observe it to make sure it is working properly, by
asking someone to turn the air-cond switch ON-OFF. Then you can
make the adjustments on the relevant screw.
4) These adjustments screws are only valid for hot engine. If engine
is cold, there is another set of screws on the right side which
"press the pedals", and the adjustment is complicated.
