Lol. I hate it when a spring pops off and goes flying. At least you know it hit the concrete and isn't under the motor in the sled. You can probably clean that switch no problem. In your picture if you look at the little dark spots, that's what needs cleaned. Clean those contact areas up and it should be good to go. I run my viper and srx at 1500 rpm idle when good and warmed up. They usually run lower than that when cold but are fine after warmed up. The "normal" rpm is about 1800 but if it is at 1500 it has less of an idle hang when coming to a stop.
