Oil/petrol mix ratio

Can anyone tell me the correct oil/petrol mix ratio for a late 1980's Mercury 4HP aux. back-up engine?
Also correct spark-plug gap for the above engine?

Sounds like where I live. Any chance they get all the men dress up in frilly underwear. I guess you must run with the same crowd. And no I don't partake myself before you ask. having said that most of them are chefs which may explain a lot of odd tendencies.

Night all and especially to you Chewy.
