Rear hub/freewheel query
I have been reading other posts regarding hubs and play and I haven't seen an answer , please forgive me for my mechanically infancy.
I have a felt MTB (just for commuting) with felt hubs, the axle was replace a number of years ago following a manufacturing fault. I tightened the cone the other day to mend play that was allowing the wheel to rub the chain stays at points but I now have an issue with back pedalling with the chain being sucked. The chain is chain is clean as are all the sprockets and freewheel. The other night when I was nursing it home I was pedalling forward and got no traction at all, the pedals and chain were spinning but the wheel wasn't. It appears to be intermittent though as after walking the last mile it seemed fine when inspecting at home.
Please help, thanks in advance.
