Choke works by electricity and bimetallic strip, current passed through cause spring to contract and open flaps. As such it's not engine temperature dependent and people find it is on when they don't need it. I've used auto Holleys for years and simply turn on the ignition a couple of minutes before I'm ready to go they are adjustable to minimise /maximise the time they are on.
