Subject: [CR] Shimano Spring-loaded barcon setup?


I recently picked up a pair of the old Shimano barcon shift levers -- pre-indexing -- the ones that are spring-loaded. Not really sure about how to set them up. They can be completely disassembled, but it seems that depending on which way you install the spring, the lever will want to gravitate/return to the "up" position, or to the "down" position (I don't currently have them hooked up with cables and derailluers -- so I don't know if that will change anything). And if I tighten the screws enough so the levers don't gravitate, then they won't move at all. Does anyone on the list know the right way to set these up? It seems like I'm either going to be pulling up against the spring, or pushing down against the spring -- which way should these work?  I've used the classic SunTour power ratchet ones (love 'em) and I thought these might be pretty similar, but they actually seem very different. Any help from listmembers?

thanks,
