Street Fighter II has 27 inch legs. The manual will confirm.

It is also one of the faster GTB SYS3 machines - I really enjoyed mine when I owned it. If the flippers have no "grunt" you will need to check that the right coils are fitted, the EOS is gapped and that they move easily by hand. The right ramp shot to the mini playfield should be easily done after a good reconditioning. Playfield polish and wax is the way to go !

Just buy new balls for your game
