I have a 8.5 hp craftman snowblower would someone please tell me, how to adjust the auger drive clutch cable thank you.

Either bend the tang that the cable runs through, or adjust at one or both ends of the cable. I of course am guessing on this one as we do not have a need for snowblowers here, sorry.

Are you talikng about the spring cable that engages the auger? There is a screw that clamps the spring shield on the outside of the cable. Lossen the screw and pull out a small amount of shield then reclamp.
