im building my first ka and its still on the stand, well while I was putting the front covers on tonight I decided to see what the compression was like so I stuck my finger in the spark plug hole and turned the crank. there was a little bit of compression but most of it blew out the crankcase. I know I haven't ran it up yet and the rings aren't seated but shouldn't it hold more pressure than that?

The engine will turn over quite a bit quicker than by hand. I'd break the engine in and then check your compression.
