Background: The RETROL team dedicated four months to crafting and designing the innovative HM-01 engine model. This model features a visible adjustable-flow main oil cup, a redesigned carburetor, and a resonance exhaust pipe. The engine boasts practical power output facilitated by its impeccably balanced enormous flywheels, equipped with a spring-loaded ball and a split widen pulley. A unique "fast-slow switch gear" has been specially engineered to accommodate speed transitions—from super-slow for precision control to high speeds for optimal power output. Craftsmanship-wise, the entire model undergoes electrophoretic surface treatment in striking red, with key components such as the body, flywheel, and connecting rod cast in durable 304 stainless steel. All assembly surfaces are meticulously CNC precision processed, while the crankshaft is forged from high-carbon steel and hardened.
