A piece of the outer rim of the plastic hub broke away and allowed the spring to jump out of the hole in the hub.
It bent the spring, and it was impossible to bend back into useable shape.
I have older McCullochs, Jonsereds, Stihles that have even bigger motors and they do not needs such foolishness to work well.
The only advantage I see, is that the spring takes up some shock, and allows the use of a smaller diameter (weaker) pull cord.
If I could replace the hub and spring and spool with a one piece spool from an older Poulan I would do it in a minute.

Yeah I hear you. Its a homeowner saw, lots of homeowners like stuff like that ez start or whatever you call it. The low end Stihls and others come with it to now days. Your saw has a 2 year warranty, did you use it?
