4-Stroke Single-Cylinder 31cc Gasoline Engine — 6500RPM Pull Start

Compact, durable construction: Built from plastic and aluminum, this four-stroke engine combines high hardness with anti-corrosion and rust-resistant properties for extended service life. Reliable power and efficiency: The 31cc displacement delivers strong output at up to 6500RPM to tackle tasks quickly. Fuel economy is improved with a consumption rate of 480g/kw.h, helping reduce gasoline use during operation. Lubrication & starting: A dedicated oil pump and oil passage supply lubrication to all required components. Starting is handled by a hand pull starter for straightforward, manual ignition. Translucent fuel tank: The clear fuel reservoir holds 0.237 gallons and provides roughly 1 hour of run time after refueling, while its see-through design makes level checks simple. Cooling & durability: This air-cooled engine features a hollow housing design that promotes airflow and helps prevent overheating during extended use. Ease of maintenance: Smooth surfaces and a simple layout make access and cleaning easy — just wipe with a towel. Packaging protection: Products are shipped cushioned in an air column bag to minimize transport damage. Additional details: Single cylinder configuration helps the crankshaft maintain a more uniform angular speed for smoother running. The fuel tank cap uses an anti-slip design to increase grip and make refueling easier.
