Guessing you have a couple of wires crossed. The mag can only go on one way, giving spark, but if the polarity is reversed it's at the bottom of the stroke.

Check the reed valve. It doesn't sound like it's closing. It may be located in the carburetor. The reed valve is a check valve. It allows fuel/air mixture from the carburetor to enter the crankcase and be compressed for later routing to the cylinder. When the piston is on the down stroke, it compresses the fuel/air mixture in the crankcase. When the piston is at the bottom of its travel, it exposes a port that allows the compressed mixture to enter the cylinder, forcing out the previously burned fuel. If the reed valve doesn't close, the piston can't compress the fuel/air mixture in the crankcase. Google "2-stroke engine theory of operation"
