A separate bracket with four fuel jets is bolted to the cylinder head. Four suction tubes are also fixed on the bracket, connected to the cylinder head with rubber fittings. Long profiled tubes with a diameter of 40 mm are pulled through the cylinder head and inserted with flared ends into the suction drum.
A pressure regulator is embedded in the fuel distributor bar, made of alloy steel. The throttle body is heated to prevent freezing.
The air line from the air filter to the throttle body consists of two parts. The elastic part provides the possibility of oscillation between the engine and the air filter; in the part fixed to the engine, there is also an inlet for ventilation of the crankcase.
The exhaust manifold is a cast iron with a flange for connecting the elastic element of the front of the exhaust pipe. There are six bolts on the flange. The exhaust manifold is mounted with its holes on the screwed bolts of the cylinder head and screwed on with nuts. A seal is laid between the head and the manifold.
