The factory recommended TBO is rated at 1000hrs @ 75% power. Standard equipment includes a fuel pump, spark plugs, air filter, recoil starter, a complete exhaust system, and dual CDI ignition for added reliability. Standard mounting is plate type from the bottom of the engine. The F33 is available in Recoil Start Only.
