Introduction
This Powerhorse OHV Horizontal Engine is an easy-to-install solution for small engine needs. With 420cc, 12.5 HP and 18 ft.-lbs. of torque, this 1000-hour engine provides enough power to run a wide range of equipment, including log splitters and pressure washers. Its patented design incorporates an industrial-strength cast iron cylinder sleeve, dual ball bearing forged-steel crankshafts and an internal oil splash enhancement system. Low-oil shutdown turns the engine off if it runs low on oil, preventing serious damage or failure. The recoil start has a compression release that helps you get running on the first pull. Combine these features with thorough U.S.-based testing, dedicated customer/tech support and incredible value, and you'll own one of the most reliable engines in the industry.

Troubleshooting
If the engine fails to start, check the fuel level and ensure the fuel valve is open. Verify that the engine switch is in the 'ON' position and the key is fully inserted.
