I run an early 70's 4hsp Evy, at 50:1. Hopefully someone can get more specific for you motor.

We've got a 6 HP, it's from 65 or 66 and it's 50:1. It still runs great!

I have a 1958 7 1/2 with the twin fuel line.
At the time of manufacture it was recommended 25 : 1. This rato is printed on the fuel tank.
With the newer oils I suppose 50 : 1 won't hurt.
