*Should have mentioned that there isn't a threaded hole for a screw*
The choke will never heat up if it's not bolted down securely to the flat spot on the manifold.

Clean the flat spot on the manifold, drill/tap the area for the hole, bolt it down and try again.

Also, the thickness of the carb gasket comes into play, if it's a new choke then you need an OEM equivalent thickness gasket for starters if you don't have one already.

The application for the choke stove/coil, linkage rod need to match the application for the gasket. Some years had a "sandwich" gasket with a thin metal center, not sure if they are the same thickness.
