You want about three wraps minimum around the small spring spool when the cord is completely pulled out if I recall correctly. Whichever the spool is that has the least amount of spring wraps when the cord is completely pulled out (my memory is not the best anymore unless I'm working on something). Of course, you have to repair anything that's broken too, like those posts.
A lot of Elux's were thrown in closets when the recoils quit working. If the local dealer wasn't on top of checking on past customers, the tanks had dim fates. I don't even want to think how many Elux tanks went to the landfill for minor problems.
