It should have a spring - at least the earlier ones did (as do practically all clutch masters). Good luck bleeding - I hate doing 9k clutch bleeding - they're worse than a C900, even with a pressure bleeder. BTW, if you haven't replaced your slave, there's a good chance it will fail soon :-( They seem to always fail shortly after you replace the master (maybe it's having new brake fluid in there, I don't know). -- Grunff
