I have a holley 650 & need a choke - how do electric chokes work & are they better than the reg coil type?

just a suggestion, does your wiring harness have a connection for an electric choke? if not i would stick to the coil setup. why add a electric choke and create another location for a possible problem. just my 2 cents, with that and a 1.50 you can buy a cup of coffee.
