How does a Weber electric choke work?

How do you lean out a carb at idle?
The first thing to do is not setup the idle speed, rather to set the idle mixture screw to lean best idle setting. First, turn in the mixture screw until the engine dies, or runs worse, then back out the screw (recommend turning 1/4 to 1/2 turns at a time). The engine should pick up speed and begin to smooth out.
What is the difference between electric choke and manual?
Manually – A manual choke is controlled by a lever on the side of the carb. A lever or knob inside the vehicle is then attached by a cable. This requires a person inside the car to slowly open the choke by hand. Automatically – An automatic choke uses a metal spring to open and close the choke plate.
How do I know if my electric choke is working?
With a meter or a test light, make sure you have power going through the green wire connected to the choke assembly. If not, find out why you have no power there. If you do, put the wire back on and watch the upper choke plate. It should slowly open up and be fully opened within a couple of minutes.
Should choke be open or closed?
When it is warm, the fuel can evaporate quickly. It is recommended you close the choke the most if the engine is cold outside and it is warming outside. You should complete the choke refreeze if your choke is warm or cold.
How long should electric choke stay on?
3 minutes is about right, but you have 3 adjustments you can make to tailor it to your needs: 1. Fast idle rpm. You can set this anywhere you want with the screw located on the passenger side of the carb just under the choke housing.

For electric choke hookup, attach the bayonet end of the long electrical lead supplied to the positive terminal on the choke cap. The other end must be connected to an ignition activated 12-volt source. The distributor side of the ignition coil is NOT a 12- volt source. It is a 7-9-volt source after cranking.
What would be the effects of a sticking automatic choke?
More gas goes in, which is what you want for cold starting. As the engine warms, the flap opens to let the engine breathe more air. If the choke valve sticks, the mixture will stay rich. Your warmed-up car will be hard to start, run poorly and waste precious gasoline.
What is electric choke?
An inductor that is used to prevent electric signals and energy from being transmitted along undesired paths or into inappropriate parts of an electric circuit or system. Power-supply chokes prevent alternating-current components, inherent to a power supply, from entering the electronic equipment.

Set the idle speed screw(not L or H) so it is just able to idle by itself. This screw will have a “stop” it rests against.

Why is smoke coming out of my carburetor?
