A syringe will not do the job. Use a very small bottle or can that is vented to outside air as a tank. The fuel tube literally sucks the fuel from the tank.

The moving thing is a piston. It has a connecting rod that connects it to the crankshaft (the part that makes the propeller rotate). As the crankshaft rotates, the piston will go up. This creates a vacuum in the crankcase. At a certain point the rotor (inside the engine) uncovers a hole to the venturi. The vacuum in the crankcase pulls air in. The moving air causes a vacuum at the spraybar hole which pulls fuel from the tank. How much fuel is regulated by the needle valve. As the fuel is pulled into the venturi, it is mixed with the air that is going into the crankcase. As the rotor moves further, the hole moves past the venturi and the process stops. By now the piston is moving down. As this happens, the air and fuel in the crankcase are being compressed. As the piston moves further down the exhaust is uncovered and the gases that were burned in the cylinder when the piston went up the last time are pushed out. As the piston moves further down it uncovers the bypass which allows the compressed mixture in the crankcase to be pushed up into the cylinder. As the piston continues up again, the bypass is closed off, the exhaust is closed off and the fuel/air mixture in the cylinder is compressed. At a point determined by the compression setting the mixture will be compressed so much that it will burn (explode, fire). This will cause the piston to be forced down.

Remember that as the piston is going down due to the expanding gases, another charge of fuel/air has entered the crankcase by way of the venturi and is being compressed. And the process continues.

Ignition improver will help, but you should be able to run without it. I have no idea where you can get things. Actually, forgive my ignorance, but I do not know where Estonia is located.

Did you get a drawing of the inside of the Mk-17 when you bought it?
