Speedy, The Pope manual for that model states 62.5 to 1. See my screenshot from the manual posted above. Bit of contention on Google about how many ml there are to a pint exactly, so around about 61 to 1.
16:1 seems a bit light on the oil to me.
Think I will go with Tyler's suggestion of 40 to 1 using a modern semi-synthetic (ByNorm) and see how she goes.
