Every time I have the carb off I adjust the idle screw, getting those little
slots in the bore just right.
But when I adjust the carb on the car that setting gets invariably lost.
So today I took the carb off sat it on the stand and set the idle screw to just touching, like this.

Then I counted the turns to get the slots right, on this carb it was just half a turn, waaaaay off what I actually thought it was.
You might have to figure in the return spring tension when the carb is back on the motor, quarter turn I reckon.
In my case it didīnt need it.
Now if I lose my adjustment with the carb on the motor I can reset to just touching and add my half turn.
