I put in a king cobra clutch roughly 1200 miles ago, after my stock throwout bearing took a crap. I broke it in corectly for 500 miles. Nothing started untill 800-1000 miles on it. Now when I take off slowly i feel a small vibration, and just this week it started when I crank the car, I can feel a very small something under the car. fells like something wobbleing. It doesnt seem too bad, barely noticable. But it bothers me not knowing what it is. BTW I cheked my flywheel for hot spots and it looked really good so I didnt get it resurfaced. Anyone know what my problem is?
