Just picked up one of these a few days ago and am getting ready to start it soon. I’m wanting to try synthetic oil but wondering about the ratio, is synthetic 24:1 too much?

Make sure it is outboard oil. Should be marked TC-W3. 24:1 is correct.

Ah ok, thank you

I run all my 1950's 3hp motors 16:1.
