1977 johnson stinger

[Fencerspinley]

Alright guys I just bought a new to me boat and it has a 1977 Johnson stinger 75 hp on it. I was wondering if there was a specific oil and gas mixture or if I just use straight gas. Kind of a noob question so keep the answers clean haha. Thanks guys!

50 to1 but it doesn't hurt to use a little richer,say 35 oe 40 to1.

I am using about 40:1 on mine now but 50:1 is the proper amount. I like to run it a little richer.
