Real good point mentioned in post 4.

New divorced chokes need to be adjusted.

There rod coming up needs to be set so when cold the choke closes off all the way.
Once the engine starts and makes vacuum the pull off should open the choke no more then the distance of about 1/8”.

A drill bit is a good gauge for this setting.

This setting should keep the motor at your needed high idle setting.

If you have a good size Cam that choke opening may need to be bigger then 1/8”.

This adjustment needs to be played with because you want the choke to come off as soon as possible so you limit that rich running condition that ware’s out rings and cylinder walls .

Depending on where you live you might want a summer setting for the choke and then one for spring and fall driving.

Note that test done 5 decades ago showed that a engine experiences 60% of its ware during the time span from being cold to being fully up to normal temperature.

Start it and drive it!

Don’t let the car sit at a high idle for 5 minutes until the choke will drop out
