Default Spark lever position at idle and temperature sensitivity

I have two questions:
1. How far down do you put your spark lever when you're idling?

2. How sensitive is your car to temp swings day to day?

I'm trying to get that nice low classic Model A idle and avoid gear clash when putting it into first when stopped. I'll get it set nice one day. Then the next day the temp will drop or rise 10 degrees and either the idle quality will drop and it'll miss intermittently or the idle speed will be higher than it was previously

Are these really that sensitive or am I doing something wrong? I only make adjustments with the car fully warmed up and I never have to adjust the fuel screw more than 1/3 of a turn or the idle speed screw much more than 1/8 of a turn.

I generally keep my timing lever ~1/4 way down at idle. Thats where I keep it when setting my idle too. I've gone through the whole ignition system and have initial timing set to 0*, I have a marvel carburetor on it which has been gone through and cleaned as well
