.Motorcycle Engine:

The cylinder body is level, so that the cylinder can avoid obstacles on the front wheels of the motorcycle and obtain good air-cooled heat dissipation performance.

.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. The flywheel rotates clockwise multiple times on the right side of the engine (the surface of the power switch), its function can make the mixed fuel completely enter the cylinder and ensure that there is no air in the fuel pipe;

(3) Turn on the power switch, and then quickly turn the flywheel clockwise to stop the engine Start the engine on the right side (surface of the power switch)

(1) If the ignition device is normal and the cylinder compression is normal, and the machine cannot start normally, it is likely to need to adjust the carburetor oil needle;

No electric start needed.

Mine starts from hand after the first spin.
I love the boxer sound. That was the reason I bought this engine for my small collection.
When I was younger I had a BMW Boxer motorbike.
If you take of the cylinderhead cover it looks nearly the same as a BMW. Very well made. I like the engine.
Carburettor could be a better one. But, I would buy this engine again.
I will make a video on Youtube.

Un démarreur électrique

Un démarreur électrique comme sur les FS 100 aurait été bien, ou que le volant soit munis de crantages pour courroie ? le démarreur aurait été bien disposé sous le moteur, caché dans le socle en bois, avec son vario de commande.
