R90S Mini Gasoline Engine 2-Cylinder 4-Stroke Motorcycle Internal Combustion Engine Toys

Motorcycle Engine:
The cylinder body is level, allowing the cylinder to avoid obstacles on the front wheels of the motorcycle and achieve good air-cooled heat dissipation performance. Two symmetrical exhaust pipes are one of the hallmarks of a horizontally opposed engine. The model's ingenious structural design ensures that every component accurately restores the mechanical principles. This is an all-metal engine model that can be started and operated.

Sophisticated Manufacturing:
We use precision casting for the entire engine, and each part is carefully crafted. The cylinder's contour and the casting process of other parts are very round, reflecting the most significant features of motorcycles from that era. You will feel the unique charm brought by the mechanical operation of the engine.

Steps to Start the Engine:

1. Check the engine wiring from the wooden base, connect the fuel tank oil pipe, and install 3 AA batteries (4.5V).
2. Fill the fuel tank with 95# gasoline. Rotate the flywheel clockwise multiple times on the right side of the engine (the surface of the power switch). This ensures the mixed fuel completely enters the cylinder and there is no air in the fuel pipe.
3. Turn on the power switch, then quickly turn the flywheel clockwise to start the engine on the right side (the surface of the power switch).

Notes:

1. If the ignition device is normal and the cylinder compression is normal, but the machine cannot start, it likely needs carburetor oil needle adjustment.
2. After tightening the main oil needle on the carburetor, loosen it by 1/4 turn and start the flywheel to achieve the normal working gasoline-air mix ratio.
3. When the machine stops running, turn off the power switch.

Superb Model Gift:
This is an amazing mechanical craft, allowing you to feel the engine's charm when working. It is suitable for personal use or as a high-end model gift for friends, family members, and model enthusiasts during major festivals.
