clutch help 12 sba

[a2jet16v]

belt is slipping in the primary, only on the bottom thou. leaving alot of rubber on both inner and outer sheaves. first thought was alingment was off. i have tried to tighten the belt up and loosen it neither of which helped. i have a 140 start rate in there for a spring. its not slipping in the secondary. i have not measured the clutch to see how much gap is in between the clutch and belt.

Does the track creep when the rear end is suspended? My 09 is way tight and squeals someitmes. If too tight it will pull rubber off the belt because it is always rubbing. I would check clearance with a new belt and make sure it's not too tight.
