Servis fridge. Always very cold and compressor on. Replaced thermostat,

There are two adjustments screws, a small brass one apparently moving
contacts and a larger screw working against a spring. Having fiddled with
these the fridge is better, but how do I adjust this properly?

Thanks,

I am adjusting a thermostat in a lada fridge there are 3 screws
1 contact spacing I think is hysteresis and temp
2 coil spring i think is course temp
3 leaf spring is fine temp
I am not a refrigeration engineer but manage to repair most things.
