So I just tuned up the rig and have noticed a noise that sounds like a ticking with a bit of jittering in it. It goes away when I depress the clutch. Actually if I just press the clutch an inch or so it goes away. The clutch was rebuilt about 2 years ago (mechanic, not me). I have been learning my 60 as I go and this is the first time I have had to think about the clutch. Any help is much appreciated.
