Hi Robin
I wired in my electric choke on the holley, and it worked OK, but when I realised how much power is was drawing constantly from the electrical system (I dont remember the figures) I decided a manual choke was better (especially if you have a dynamo fitted). I already had a choke cable fitted to the car, from a previous owner, in the position below and in between the fuel gauge and clock.

Also any automatic choke on a classic car can be unreliable, so I prefer a manual one. But nowadays, with fuel injection on modern cars, a cold start enrichment is an integral part of the system.
