I use electric if a choke is needed. Too many times I have found myself or customers who hit the cable or forgot about it and ended up fouling plugs and stuff. I just prefer the "pump it twice and hit the key" deal. Otherwise, I wire them wide open and dont run a choke. I have a choke on my truck, and I think one or two cars over the years I've installed chokes on. For the most part, you dont need it unless you're cold starting in weather below 40°.
