How to adjust idle(cold) RPM cuore?

[ToxicDevil]

When the car is cold the idle is way too high. So high that it is very very difficult to drive the car, as it is auto.
When the car gets hot the idle gets perfect, but it takes around 10km drive to get it heated up to that temperature.

How to adjust it?

I forgot to mention it is on petrol and the setting are done on petrol and there is no air blockage.

i think u should get ur mixture setting redone by a professional carby mechanic! just my idea

[ToxicDevil]

The mixture and idle(hot) settings are good.
Could it be a problem with choke?

@ToxicDevil I am also having same issue. Did you find any solution? If you fixed the issue please guide me. I was having problem with carburetor and I replacced with a KABLI. now having rpm issue when cold. Also when it got hot rpm drop low.

if the thermostat isnt there,the temperature wont reach optimum level and will keep the choke engaged. how many minutes does it take for the temperature needle to rise about 25% of the total?

[ali_engr]

thermostat for radiator fan is auto and that works. Initially if I start cold car and leave it would take more then 20 minutes to move temperature needle from the intial location to the bottom line of C(Jahan sy C ki line shoro hoti hy wahan tak punchy tak bahot time lagta hy), if needle reach the start line of C then rmp go down but after that when move in 3rd or above gear, needle goes down below the cool(C) position and again RPM goes on high.

Are you sure the thermostat valve is in there?

And i think the fast idle is adjustable. Coure owners may know about it.

But your problem is the engine not getting warm enough.

yes, thermostat for radiator fan is there, tested it fan started when temperature needle reach to middle(only possible when stuck in traffic or stop for longer time).
Is there any other thermostate for choke as well?

T valve is not present. Get it installed.

Either your Thermostat valve is stuck open ( I had that problem with My Alto VXR twice) or Thermostat is not installed in the first place. Temprature drop is only caused by Absence/Fault of Thermostat..

You are mixing up the two things. Auto fan switch is separate circuit and thermostat valve is separate flow control setup.

The fan switching on automatically is due to temperate controlled switch which closes the circuit when coolant temperature crosses a set point, say 89 deg. C.

The thermostat valve is a valve which start to allow coolant flow towards radiator when the coolant temperature crosses a set point, say 82 deg. C.

I would say again, check for presence of thermostat valve, and/or its proper functioning.

@metalhead

Thanks for guidance. Issue was with thermostat valve. now working fine.

Faulty or missing?

Anyways, good to know that your problem solved.

[ali_engr]

Is there a way to adjust auto choke RPM when start cold. Its very high on start for about 7-10 minutes. Can it be adjust to low with electric auto choke in cuore. mechanic says it can not.

[margallar]

Choke is adjustable and this looks like choke problem

[aamirq]

Check engine coolant temp sensor if that's faulty it takes a lot of time for the car to warm up

[ali_engr]

Can somebody please post picture & position of the screw where from choke is adjustable?

Which one is "engine coolant temp sensor", please mention in picture.

Thanks,

From you get and ref any good mechanic?
