Does the system use an oil injection device, or does the fuel have to be pre-mixed?

The fa50 has a oil injection system CLICK but older systems can be problematic - so pre-mixed could be an option

As Markus already answered, the FA50 has an oil injection system. However, several users on Moped Army advise to bypass the oil injection system and just premix the fuel – it will supposedly regain a bit of power lost from powering the pump. I am looking into creating a guide for this procedure, but it will be a while before I get a chance to sit down and figure it out.

Het is mogelijk benzine en Olie 2takt vooraf gemengd te vullen in de benzinetank ? Gedaan En Wat Met De olieinjectie ?

I just bought two 1985 fa50s. Has old gas that needs to be drained. I had the same question regarding the mix. Also, does these babies have a fuel filter? Also, a oil filter? And what is a good oil to use?
