Edelbrock 1406 electric choke/fast idle

Grounded to carb stud, 16 guage wire from t-stat to fusebox (keyed power). After truck is warmed up should the choke be straight up/down or about halfway open?

Mine is halfway open and wondering if this is right or does it need adjusting? If it needs adjusting does it need to be richened or leaned out?

And would someone explain the 'fast idle'? Ive looked at the videos but it didnt have much on the setting of the electric choke.

The notch on the black housing is in the exact center of lean/rich.

Thank you.

 

Should be fully open when warm, straight up. back off the spring tension on the electric coil housing, loosen the three little screws and rotate the housing towards lean. The fast idle is controlled by thhe small screw on the bottom of the arm where the cable hooks up, increase or decrease as required

 

So straight up and down. Got it thanks! I'll report back if more questions. Fully warm is 190 (when t stat opens right?)

 

With an electric choke "fully warm" on the choke isn't directly related to engine temp, just how long you've been feeding power to the choke heater. But by the time the thermostat opens the choke should be open. Really should be open before that.

 

Ok, but it when its open it should be straight up/down

 

Pretty close to that. I've got the same issue on mine so it may be a common issue.

 

I'll tinker some more im learning on the choke i had it just manual choke but i figured it be nice for electric to work so i started to hook it up its pretty simple once you sorta understand how it works.

mr chevy-your choke ISNT straight up/down or it IS straight up down?

Performance wise I cant tell the chokes not open all the way (i guess my mpg may suffer slightly)?

 

is this a new carb or one that the choke has never been hooked up?

 

New to me carb.

I dont know if my buddy ever had the choke hooked up (probably not) lol

 

I don't honestly know. I spend most of the day repairing the cord on my daughters hair straightener and then trying to get my heater to actually put out some heat and get the blower to work. I figured out the vibration in the heater blower though, a mouse had eaten a hole in the squirrel cage fan.

 

huh lol

 

Heres what I do to every Edelbrock carb I use.

Connect the electric choke ground to a carb mounting bolt, and to power "only" when key is on engine running, engine off = power off so no chance of ground short.

Warm the car up and lean (open) the throttle plate so that it's straight up and down while running.

Shut the car off and turn both fuel/air screws in all the way, then back our 5/8 on both sides.

Start the car and readjust fast idle while cold, then readjust normal idle once warm.
It's worked for me on 6 cars and I get around 18 miles to the gallon.

 

i asked if the carb was new as the bimetallic coil will loose it's range over time, or number of cycles, i just looked to see if i could email edelbrock to ask what the number of degrees of rotation the coil should have from cold to hot, of course there is no email address, there is probly only two people with that company who would know the answer anyway..lol

 

i tried callin tech support and waited for over 10 minutes so i gave up.

 

Usually the choke (the black housing w/white mark) will be in the center of the lean/rich range - they been making those things for decades and if you are much off center then you've got something wrong. As others said, there is a heating element inside that housing (give it a few minutes and touch it, it'll be warm; if you wait too long it'll be hot) and the choke opening is independant of the engine temp. To adjust high speed idle, turn the engine off and rotate the accelerator linkage plate & standing from the front you will see a screw head rotate into view - this is the high idle adjustment, turn in for higher and out to lessen.

 

Ok, So really I need to wait till a good cold day to really set it? Also, can I set it for the winter and just unplug it from the fusebox in the summer/warm days?
