Thanks very much Dieselboy and Mark, your help is much appreciated. it seems like a bloody complicated process to me. I was given the rideo-on about a week ago from the inlaws, by all accounts it runs needs a battery and came with a new drive clutch cone which does need replacing before using, but no instructions, the fellow it was brought from said you just undo a screw here and there and bobs your uncle, no wonder it was cheap lol, oh well i am gonna have a crack at it, thanks again guys.
