This state-of-the-art power base is a 208cc OHV, all-season 4-cycle engine. The rugged Latch 'n Lock' system has endured the Troy-Bilt® test of quality, with hundreds of hours of accelerated use - and is fully integrated with a self-propelled transmission for easy operation.
It is recommended to always inspect the spark plug before each use and every 25 hours of operation. When the spark plug is ready to be changed, make sure that the engine is upright and level. It is best to change the spark plug after every 100 hours of use or every season.
