First of all, in 1965 no gasoline had any Deposit Cleaner Additive (aka Techron). All name brand gasolines today have anti-oxidants, corrosion inhibitors and deposit control additives. Sure, in extreme cases you can use a fuel/carb cleaner and see improvements. For the normal day-to-day stuff it is a feel-good thing. Emotionally you know you spent some money and you really think it helped. But really, it did not help anything! Water is by far our biggest worry with 10% ethanol. Keep the water out and you won't have any problems. Since most of us park our Cobras inside, we don't have anything to worry about. Has anyone had problems with their Cobra in the spring after sitting around all winter? I would like to know.
