I retro fitted an electric choke on my Holley 4000 (55 Tbird).  I bought an inexpensive choke from Amazon to see if I like it.

I had to bend the tab to wrap around the lever in the choke housing.   I connected it to 12 V to test it and see if the spring was moving in the correct direction.   The black housing was very warm, to the point I couldn't keep my hand on it for very long.   I never used an electric choke.  I know the technology is using current through the bimetalic spring which in turn would create some heat.  I am wondering if it's too hot???
