adjust clutch

So I have a 1998 Honda Recon fourtrax and it will not move, but it runs, everything I've seen is people saying that it could be the clutch gear adjustment, is this right? If so, how would you adjust the clutch gears since I don't have a clutch adjuster?

I have missplaced my manual, on the external adjustment what are the number of turns on the external clutch adjustment screw, before tightening the locking nut? Thanks ... Gary
