HI all. I just acquired my first 1981 C70 passport and was doing some general maintenance when something got me puzzled: I see oil when I remove the oil stick but I don't seem to be able to drain it when I remove the oil pan bolt!
After removing fully the bolt, only a cple drop came down. I looked inside with a flash light and can see a screw that brings down some sort of cylinder that holds a spring, when you unscrew it.
Being my first encounter with this type of moped, I thought I would seek your expert opinion about what to do.
