There is a small design flaw in the starter bottom switch where the return spring is to stiff and over time it'll cause the plastic mounting plate to fracture. MP promptly sent me a new one and I crushed the spring so I don't have to push as hard thus reducing the stress on the plate. It may have just been the one I received but the way its design I'd say don't take the chance and weaken your spring before you have any problems. When you take it apart its not complicated but be sure not to lose any of the tiny parts.
