common prob even with new kit , after rebuild put a new mikes starter kit in and within 200miles doing the same , didn't realise at the time even mikes new kit spring needs to be tensioned most of the time (let alone the old spring) theres a couple of write ups here on it including about some models you have to reposion the spring end .. I keep meaning to redo mine but I'm lazy and waiting for another reason to take the clutch apart first
