i'm re-reading my original posting and it may not have been too clear. with the engine not running and the rack raised, makes sure the spindle can be spun freely by hand with no metal on metal sounds. if you do hear/feel metal on metal, loosen the (4) engine mounting screws and rotate the clutch drum housing. look very closely and there should be (4) slight marks on the clutch drum housing where Staton wants you to position the mounting screws. most clutch noise on the Staton kits is due to the engine clutch not being perfectly centered within the clutch drum. i've had situations where it may be centered but the clutch bolts on the engine protrudes too much and hits the inside of the clutch drum. you solve this by inserting a washer underneath each engine mounting screw between the engine and the clutch drum housing, just enough to give the clutch bolts clearance to the clutch drum so that it spins freely. Staton kits are extremely reliable and problem free with the engine properly mounted.
