Rear Shift Problem

edited May 2010 in Workshop
I have a 10 sp Centaur rear mech and since bringing the bike back out from its winter hibernation, I've had a problem getting into the smallest gear. The chain shifts ok but it won't stay on the sprocket. Changing's all fine otherwise and I think the indexing is ok. I have fiddled with the barrel adjuster but to no avail. Any suggestions to save me a trip to LBS? Thanks.

    its either the adjuster screw needs adjusting to allow it into the small cog or the cable is not loose enough. it may be gunked up if its been left try replacing the cable if adjusting the stop screw on the mech or the adjustable barrel at the rear of the mech doesnt work.
