should be 50:1. how does it start/run? newer ones have oil mix pumps. you can get a mercury autoblend 2 unit on ebay, they will essentially do the same thing and you won't have to deal with mixing oil
some of the older 2 stroke motors came with stickers on them saying waht to mix it at. check under the cowling or other places on the motor.
a lot of the 100 to 1 motors went back to 50-1 just because letting the motors sit with out fogging them caused rust inside the motors from not enough oil during set up not during running
They labeled some engines 100:1... and rapidly found out that they were replacing engines under warranty due to lack of oil.
So they sent out service notices to the owners of those engines to use 50:1

You usually don't notice it when the boat (motorcycle... whatever) is moving.
If you're leaving a fog bank of smoke all the time... that's too much oil or maybe a carb issue.
Note: if you use regular motor oil... it will smoke A LOT... and it will be depositing stuff in the combustion chamber which will eventually cause the engine to seize due to thickness of buildup. Use a good 2-stroke oil meant to be burned. (Penzoil low ash is my preferred.)
