This is the info I found on the net. Interesting...........Terry
Electric choke.
Configure it as follows:
•Get a Relay, hook the coil up to a Switched , fused source,
•The ground to a hard ground observing good bonding practices.
•The Normally Open contact of the relay to go to the Alternator FIELD wire.
•The center wiper of the relay to the choke heater element.
In this mode of operation ,the choke element only receives power and
opens when the engine is ACTUALLY running..not while you wipe down or
scrape ice from windows with the key on and not running..
An added unplanned benefit is when the diodes in the alternator start
to break down, the relay coil will buzz..lke a mini shaver..alerting
you that something is wrong in the charging system, long before the
battery starts to die out every morning.

This is a great idea. My NAPA 2-1603 electric choke opens waaaay too soon. I thought the thing wasn't supposed to open until the manifold that it's bolted to warmed up but this is NOT how it works.

why would you leave the key on without the engine running?

C'mon Fred, I'm not stupid. I am very careful to not have the key on before the engine starts but the choke still opens before the engine is warmed up enough to run on its own. And I have a relatively recent rebuilt Paterson carb so that's not the problem.

More than once I have turned the key on to supply power for testing.
Even a few seconds, such as priming with an electric fuel pump, cuts
down on the choke time. Yes, I know that I can put the pump on a
separate switch but that part is done. Don't want to go back and
rewire the pump just so I can wire the choke differently. Besides I
like the idea of a fused relay circuit............Terry

If you want to delay your choke opening based on engine temperature, you need to get the thermister type electric choke that NAPA and Carquest sells. This model has has a sensor that bolts to the intake manifold and changes the voltage to the choke heater based on engine temperature.

Bill's choke is that type. The part number he showed is the 2-1603 NAPA Echlin, which uses a thermistor.
Bill, the rotation of the choke housing still controls the calibration of the choke, as I recall, and as seems the case looking at the picture. You still have to adjust the choke control that mounts on the carb. I adjusted mine so that it just pulled choke off all the way when fully warmed. I did this turning it so that the choke never pulled off, running the engine for 10 minutes on a warm day to ensure fully warming, and then rotating the choke controller so that it just allowed the choke to release fully.
If you have it wound too loose, it might not be fully applying choke, which means that it will release choke fully when it is supposed be a half-choke. I bet that's your problem.

at the chance of getting told this is dumb, if ur intake is blocked but
not filled, consider sticking a 1/4" brake line loop back into the
original opening for the original choke and using the original one
again. I live in Ohio and even with block off plates (and filled
crossover) my brake line thing works as good as original for the
mechanical choke without these electric issues.

I have done that in the past by wrapping the tube around the exhaust
pipe. It works but looks kinda micky mouse...........Terry

I agree that this will work fine, if you route the heating tube to the right place. My aluminum manifold warms up pretty slowly, though, and wrapping it around the exhaust header might be better. My choke tube was completely blocked before I changed the manifold, and I just jammed a piece of copper tubing down into one side of it and poked it into the opening on the carb. The copper conducted heat well enough to do the job.
But don't disparage the thermistor-controlled electric choke. When properly adjusted, that device works VERY well.
