No need for embarrassment Barit. It is a commentary though, that in this age of the jet we have forgotten the basics of what the pilot of old knew ie care, feeding and workings of the recip. From my ground school commercial pilot notes (when the big recip was on it's last legs airline wise, but still plentiful in the military - C121, C97, S2, A26, A1, T28, and more.
Perhaps I should add that the above course notes were written by C. S. Hames, who joined the RAF as an engine apprentice in 1938, on completion of that course remustered as aircrew, trained in the USA, flew operations over Europe during WWII, was part of the Japan occupation force and subsequently graduated from CFS as an instructor.
