Well, I did fly gliders (from a winch site) before getting a PPL in the late'70s. Maybe cable break practice contributes, but really I think if you have lots of practice EFATOs in a powered aircraft that should make it instinctive. And instinctive it has to be - there isn't time to sit and work it out when it happens.
Perhaps flying an aeroplane with an ancient design of engine helps as well (Gipsy Major) as these are more prone to occasional rough running and misfire than later designs such as Lycomings. When this happens, one automatically eases the nose down a tad in the climb to compensate for any power loss.
