Well, I found a few manuals for similar models - and one for the motor (it is the Minarelli V1) - so, started kind of going over it. I've done a few old tractors and some 70s snowmobiles, so - not my first adventure in getting and old machine going, but my first moped.
The front tire holds air, the rear is shot. I'm holding off on purchasing anything for it, because it appears the motor, which I thought was free, seems to have a stuck piston. I put the bike on end and pulled the carb and head, and filled the cylinder with seafoam, so - we'll see if that gets it to loosen up. Other trouble is the screws/bolts that hold the housing to get at the ignition seem rusted solid, so - put some penetrating oil on them, if they don't let go - I guess I'll just drill them out.
Put oil on all the bolts, you never know what's going to get taken apart - so, I just always do that on an old machine that I'm trying to go over. The right foot rest is missing, and the front bracket that is on the frame is broken off.
No brake cables. Pulled the lights off, so I don't break them horsing the thing around, tail/brake light is missing lens.
Gas tank rusted, and had old gas. Pulled tank off bike and started juggling some old nuts and bolts to loosen up the rust.
Only had one chain, that was broken, so - would need new ones. No speedo cable.
Drained the oil and filled with fresh 30 weight.
Guess I'll have to see if the piston frees up. I've rebuilt a few motors, but never seen a stuck piston before. Cylinder seems to have light surface rust, but not terrible.
