Cookie, It's lucky the CJ parts are cheap, because they certainly seem to chew through a lot of them. One of my chums runs a bike shop here in Hong Kong and has quite a few clients with them, there are always one or two in the shop, they have frequent problems and the quality of replacement parts is generally quite poor. He has found that the older 6volt side-valve models are less problematic than the later ones. I know you have a couple of these, hopefully your own mechanical ability helps you to keep them serviceable.
