Motorcycle Repair: CB 250 1977 electric start, fly wheel, rubber hammer

Question
Hi!
1977 CB250. Electric start. Bought it, started fine. Now, three days later, all i
get when i press the button is a clicking sound, seeming to eminate from a
small round cylinder between the battery and the engine. Any help greatly
appreciated. I'm told hitting it with a rubber hammer would help, and i'm
guessing something along the lines of starter motor - 'fly wheel', not aligned.
Thanks for yourr time.
