RETROL ENGINE HM-01 7cc Engine 4-stroke Horizontal Hit and Miss Internal Combustion Engine Model

Introduction:

The RETROL team has spent 4 months designing and developing this new Hit & Miss engine model, designated as "HM-01". This hit and miss engine adopts carefully selected high-quality materials and exquisite craftsmanship to assure the engine's reliability and durability. The design features a transparent, adjustable flow main oil cup, a new carburettor and a reverberating exhaust pipe. The two large flywheels are well weighted, with a spring loaded ball and split wide face pulley, making the engine very practical for power output. A special design with a rarely seen "fast and slow gear change" allows the engine to be switched between super slow speed and high speed for power output. This makes the engine more playable and the player more operational. Product technology: the whole machine Ferrari red paint using electrophoresis surface treatment process, the main components (body main body, flywheel, connecting rod, etc.) are made of stainless steel 304 casting, all assembly surface using CNC finishing, high carbon steel hardened one-piece crankshaft. This makes it not only a playable engine model, but also a highly collectible mechanical artwork.
