If you have an electrical problem in the mid-north of Ithaca - Stavros, Platrithia or Frikes, chances are you'll need Kekatos to fix it. This Exoghi local is needed by everyone all at once and thus the wait can be some time.
Apart from a short sojourn in Athens, Kekatos has spent most his life on the island. He doesn't socialize much due to his allergy to cigarette smoke, but you can see him riding the trails between jobs in his beaten up ute.
Catch him if you can.
