The engine power system includes: a fuel tank, a fuel line, a fuel pump, a carburetor with throttle and air damper drives, and an air filter with a housing.
The fuel supply is in the tank, which is installed in the trunk on the right side. Fuel from the tank through the fuel line through the fine filter enters the diaphragm pump. It is driven by an eccentric of the accessory drive shaft. When the engine is not running, fuel can be pumped into the carburetor using the pump manual drive lever. There is a hole in the outer spacer of the pump. Leakage of fuel from it indicates leakage of the pump diaphragm. Next, the fuel is fed into the carburetor.
Air enters the engine through a replaceable paper filter, the housing of which is mounted on the carburetor.
