Used Derbi Flat Reed for parts or repair.
This engine turns over and would be a decent start to build something up or finish that shelved project you've forgotten about.
Transmission looks to be complete. Engine turns over. Missing the obvious stuff like ignition, top end, 1 cylinder stud, and intake.
Probably best to rebuild before use if that is the intention.
