Sounds like you talk from Experience, I am hoping a bleed and re align the shoes is the issue, previous owner has replaced shoes, thinking may not of set them up right. or bled them..
The clutch is and odd one, Bled the SC and it was fine, the res has stayed full of Dot so that's good. but when releasing the peddle the return into the SC is unbelievably slow.
I have a ignition barrel that the key is I think snapped inside or the barrel is worn, so tried to remove this to fit a new one but cannot release the sprung ball at the moment.. so the drill might come out.
Thanks for the welcomes. hoping to get her tidied up to use her, then at somepoint I will get her the same colour inside and out. Fire brigade red inside at the moment...
