How to pick a choke:

Manual chokes allow the user to control the warm up of their engine by physically pulling a cable inside the vehicle to control the choke plate. This type of choke is generally less expensive than an electric choke.

Electric chokes fully handle the warm up of your engine without your assistance. They operate off a single 12 volt switched power wire from your vehicle.
