Clutching at straws

No sooner do I solve Snowdrop's running problems then the clutch starts to play up! It turned out to be a loss of fluid so I bought some flid and a slave cylinder repair kit when I was down at the TSSC International yesterday. When I got back I rebuilt Snowdrop's original slave cylinder and fitted it. I did a test run before I put everything back together and it seemed to be fine. When I'd finished refitting everything I took Snowdrop for anothe road test and it was like it was before I'd started. These cars can be so frustrating!
