If you are going to run a choke electric is the way to go IMO. Once it is set you you don't have to worry(or even think about it), just turn the key. From the information I have gathered you can find many parts for an ERA at several different retailers but when purchased from ERA you get the correct part & if any mods need to be done they are there with the info to get you through it or have already have it done when you get it.
