Question on an electric choke, I never had a working one before.

That first electronic control in the picture, the 6730 / 8357 part number, looks like the one I have. It does not have an external resistor.

The wire leading to mine was broken at the connector, but since I have a new wiring harness now, I just need to get a few push-on connectors at Lowes and make a wire to go from the output to the electric connector in the carburetor itself.

So if the unit cuts off power after a few minutes, then I assume the heat coming off the manifolds of a warmed up Slant Six is enough to keep the choke open until the entire engine cools down?
