So i was looking at my little engines, and im curious - How does the fuel get into the ignition chamber??

Quick answer...when the piston goes up it creates a vacuum inside the crankcase that pulls air and fuel in. When the piston goes down the mixture is compressed and pushed up into the upper cylinder through some "bypass flutes" or grooves in the side of the cylinder (between the exhaust slits).
