New summit carb. However the choke system is identical to any other full electric Holley. It was either too much tension, or not enough. It would come right back on in the winter after restarting and the high idle would be quite high when it did not need it. The high idle cams were too radical per step. It would either be fully on or it would kick off to the final one right off the bat. I got sick of that crap and went manual and love it.

What you are describing are the inherent problems with a fully electric choke. I had a Holley Avenger for a while and had similar results, no matter how I adjusted it. The stock Ford Autolite or Motorcraft carburetors used a thermostatic "hot air" automatic choke system with electric assist that works MUCH better.

I see.

The better electric chokes use a sensor that bolts to the intake to tell the heating element in the choke how warm or cool the engine actually is. Like the kit below,, I believe the little black box with the large mounting tab is the temp sensor.

Even better than that is a divorced choke that sits in the intake with electric assist. Our van has that, and it works great. Needs a new thermostat though, the electric assist quit working, but the choke will still open itself after a little while due to the bimetallic spring sitting in a cavity in the intake. ALMOST as good as hot air, but for me I like setting it myself every time. No muss, no fuss.
