Johnson 5 hp

[birdhunters]

I recently acquired a Johnson 5hp. outboard Modle #TD20 Ser# 53****. Does anyone know what year this engine was mfgd? What would the oil/gas mixture ratio be for it?

Re: Johnson 5 hp

A TD20 is 1949. Use half pint oil (8 oz) per gallon of gas. Use a Champion J6 plug gapped at .030. I think point gap is .020.
