Case Protector

When running high compression engine, starter kickback is quite common. The result? Busted engine case as show by the picture below. That happens when the starter is unable to crank start the engine and the built up stress "kicks back" onto the starter idler gear and with a weak joint holding the starter gear (on the engine case), this kickback will result in that joint breaking under stress.
