RPM Adjustment for Carby Cultus

[atifnaeemmalik]

Dear Fellows,

There are screws (with spring) on carburetor for idle adjustment on different combinations / loads e.g.

1- Normal Idle
2- Idle with AC ON
3- Idle with Headlight ON
4- Idle with AC & Headlight ON

From the attached Pics, please identify which screw is used for which scenario. it will be very helpful for cultus owners. I am not much clear that all the required screws are present in the attached pic instead of #1 which is Normal Idle a white Plastic Screw on back of the carburetor for which I was not able to take snapshot.

in second pic white plastic screw is visible (not circled), it is used for idle speed adjustment...
idle with ac on can be set by vacuum switch (not visible in pics)
while with headlights on, i am not sure if there is any adjustment screw for that

[atifnaeemmalik]

for normal idle adjustment from plastic screw, I now can identify in pic 2
If idle with AC is not visible in pics (set by vacuum switch) can you please identify the location to trace it?

i tried the white screw but it didn't work

[atifnaeemmalik]

White screw is for rpm on petrol. I have verified it. No one is answering on this thread for detailed setting which you also might require as I need

Aoa, the screw for the high to low rpm should be tight or loosen to get right setting?? I feel a huge jerk wen i release acceleratr suddenly to slow up the car.
