you need to use tcw 3 rated 2 stroke oil, not the oil for weedeaters and garden equipment. you have not hurt anything. the carbs probably need to be cleaned and rebuilt. go the engine faq forum, and use awakening a sleeping outboard. it's also time to repalce the impellar (water pump)

Standard pump unleaded fuel is fine for that outboard. Mix 50:1 with TCW-3 2 stroke oil.

This motor is probably going to need a little TLC to get it running well, if you are going to do the work yourself you will need a manual, you can normally find one on ebay.
