A youthful Nick H at my parents’ house where I am rebuilding a BSA Beagle engine. I owned 3 or 4 of these unsuccessful lightweights and my father had one too, it is probably his engine that is on the bench. If you were aware of their problems (members of the BSA Service Dept. certainly were!) and knew how to fix them they were actually quite a pleasant little bike. I commuted to work on one for quite a while.
