Starter stuck in on position

[Will N]

The repro switches have a copper strap. Copper is not springy. Original starter switches had a brass alloy strap that was much more springy. It's more yellow in color than copper. Hunt for an original switch at swap meets. Even if the shell is rusted and a mess, all you want is that original strap. You can use that in a nice repro shell if you want it to look nice.
