knob on choke cable

[Club Coupe]

I have a bad choke cable on my 1950 Ford. I can't get the old knob off. I tried screwing it off and pulling it straight off but nothing gives. What am I doing wrong? Can one of you advise me?

I have used a small propane torch to heat the metal shaft just enough to soften the plastic such that the knob will pull off.

If you want to save the knob for reuse, do what Meric42 has advised.
If you're replacing the knob, cut it off.

Thank you both. I plan to reuse the know so I will try that tomorrow.
