Wanted: Edison Fireside mainspring

[kirtley2012]

I've had a multitude of problems with my fireside, now everything boils down to it must be the mainspring, that or some kind of sorcery not allowing it to play, anyone here have a fireside mainspring for sale?

The motor runs fine on it's own, but attach the belt and bring the upper works into play it will grind to a halt, starting to seem like a weak spring to me

I have a complete Edison Standard motor that you can have for $50.I assume the mainspring in it is ok.I think the Standard mainspring would be the same.edisonplayerPS;PM sent.
