• The RETROL team spent 4 months creating and designing this brand new H&M engine model, designated as "HM-01." Adopt carefully selected high-quality materials and exquisite craftsmanship to assure the engine's dependability and longevity. With a visible adjustable-flow main oil cup, a new-style carburetor, and a resonance exhaust pipe. The engine has a practical power output because the 2 enormous flywheels are perfectly balanced and equipped with a spring-loaded ball and a split widen pulley. A one-of-a-kind "fast-slow switch gear" has been specially built to fulfill the requirements of engine speed switching at super-slow speeds or high speeds for power output, providing users with increased playability and operational experience. In terms of craftsmanship, the entire model is treated with electrophoretic surface treatment in red, and the main components (body, flywheel, connecting rod, etc.) are cast in 304 stainless steel. All assembly surfaces are CNC precision processed, and the crankshaft is made of high-carbon steel and hardened. This is not only a playable engine model but also a highly collectible mechanical artwork.
• .Notes: the RETROL HM-01 engine typically includes the engine itself. However, it does not include a fuel tank, base, or equipment wooden box,a spark plug, and a CDI igniter(will be released later). These additional items would need to be sourced separately to complete the setup and display of the engine.
