'75 Eldorado Choke (?) Adjustment

<< < (2/2)

Benji808:
This is tremendously helpful - thank you both!

old cars:
So just turn the adjustment screw on the front pull-off counter clockwise to lean the choke on cold start.
Try half turn at a time.

Benji808:
Turning the screw does not seem to have any impact on the choke blade position (after a cold start, I've taken it 3-5 turns in both directions). Would that imply that the pull-off is bad and I should replace?

Kenth:
Is the arm in pull-off pulled at all when engine is started?
If not, time for replacement.

Benji808:
Alright - it is sucking in, but I think I found the issue with the choke itself:

The inside of the choke cap has a metal coil. At the end of that metal coil is a "square" shape. Is it correct that the choke flap lever should sit INSIDE the square?

Because mine wasn't - the choke lever was resting on top of the square, so the choke could only reliably be adjusted one direction (I think I made it this way when I was messing around a couple months ago).

Started it up and it seemed to idle much smoother that first minute; I'll get more chances to test but seems like it was that simple error.
