So i’m currently running basically no choke on my Charger, 1967 383. It’s a 4 barrel carb, i got it from my grandfather a while back and it has a few problems and need help identifying them, i don’t know much, though as i wasn’t born in that era.

The left side, there is a little hole in the thing that flips the choke. any ideas on what that is?

The front, Which idle is which?

The right side, What’s the long bar with the small pole through it?

 

Welcome. Here's your basic choke operation that should explain "hole that flips the choke".

When the engine is shut off hot then cools down a choke thermostat (bi-metal coil mounted in the intake manifold) moves the lever to close the choke and allow a weighted cam to fall down against the idle speed screw. It is ready to start now.

To start, depress the gas pedal once, then the choke thermostat closes the choke fully and allows the weighted cam to drop fully and have the idle screw rest on the highest point.

Turn the key and when the engine starts it creates vacuum pulling on the diaphragm inside the choke pull off (the round thing) and pulls the choke blade slightly open. Now the engine should run at high idle speed and more rich.

As the engine warms the choke thermostat heats and it pulls on the choke lever waiting for the next time the gas pedal is depressed to fully open the choke and move the weighted cam to the lowest point for hot idle speed.

The two screws on the front are idle mixture screws, one for each half of the intake manifold. The long bar is the transmission kick down linkage which adjusts transmission fluid pressure as you drive to change how hard the transmission shifts, less pedal easy smooth shifts, more pedal hard fast shifts.

Don't forget the You Tube has many videos on idle mixture, choke and kick down linkage adjustments.
