I have an old EZ that is about 40 years old. It quit having spark so I have been searching for retailers that carry old Homelite chainsaw parts so that I can rebuild the ignition. I found a few. I had the same question. I believe through my research on line the only difference between the Super EZ and the EZ Automatic is the Automatic has automatic chain oiling. Mine has a manual oiler. I have the original parts list that came with the saw and both the Super EZ, the EZ Automatic and the Super LX Mini Automatic is covered using the same parts listing. Pictures on-line of both machines look identical except for the decal. Hope this helps.
