New Vanguard single-cylinder engines from Briggs & Stratton feature a single lever, the TransportGuard system, which simultaneously shuts off fuel and the ignition. Rental companies now have the leverage to eliminate human error — fuel stays where it belongs during transport preventing fouled plugs, hydraulic lock, cylinder wash down or crankcase oil dilution.
