4.2(3.1)kw/3600rmp Gasoline Engine

Specifications

OHV air-cooled gasoline engine, 8hp engine, both hand start engine and key start available engine. EPA and CARB approved engine.

Overhead valve is the key to SG series performance.

SG series engines yield a greater volumetric efficiency by positioning the in take and exhaust valves directly over the piston.

The resulting 8.5:1 compression ratio contributes to more complete fuel combustion and even burning for greater fuel efficiency.

Convenient oil filling and drain locations make oil changes quick and easy. The electronic ignition is maintenance free for the life of the engine.

The long life of SG series engines is attributed to superior components like: unique connecting rod, induction hardened crankshaft, cast-iron cylinder liner, valve seats of high chromium/tungsten alloy, and a high efficiency cooling fan.
