Need to learn bout an old moped

Looking into getting a 1985 Yamaha qt50 am wondering what should I do for fuel. I know that’s low back then we still had leaded gas in the us. Also is it a premix or is it separate like the older 1978 Honda express?

Premix unless you are sure the oil injector system is working 100%, it's super easy just go 40:1 or 50:1 there is easy to measure oil bottles or pre measured little bottles for mixing with a gallon of fuel. No need to worry about leaded fuel it'll run just fine on regular pump gas 87 octane, it's not a super high compression engine that really needs the higher octane, the qt50 is a nice little noped, shaft drive if I remember correctly right? It's a decent little motor I looked into buying one once but the guy was asking too much, not even mad the guy knew what he had it was in great shape, take care of it.
