No worries smile and thanks. The 1950's 4 strokes generally all have the kick start on the inboard side. The 4S20 is not a common machine - the one I have was bought from a bowling club by the previous owner. I believe that once ATCO went to recoil starters the kick start disappeared altogether. The machine that I bought had not been used for over 30 years and after a minor clean up runs like a dream.
