Well done Speedy ,this Pope definitely looks like it hasn't run for 3 decades.
16 to 1 is the correct ratio for using engine oil as 2 stroke mix. People say you get covered in smoke at this ratio.
If you use good quality 2 stroke oil you could probably get away with 32 to 1 but I ran 25 to 1 with outboard 2 stroke oil, this was just running the motor with no load but cutting grass I'd probably go 20 to 1 if it doesn't smoke too much.
