First how should my clutch cable be adjusted. I have an 89 crx si and when i got it the little black knob for the clutch cable was way loose. should it be hand tight. tight at all? or use a wrench to tighten it. second when i push in my clutch i hear a scraping shaving type of noise. at first i though it was my intake because it sounded just like it, but now im wondering if it isnt the little mettal rivets on my clutch like on breaks when they wear out too far and scrape the crap outa the roters. Any ideas?
