sewing machine

My sewing machine was acting up last night - so I took it apart and cleaned it. It still isn't working quite right, but I'll have to wait until after work to mess with it more. Now the 'jumping' it was doing from stuff clogged in there isn't happening, but the stitches won't interlock either..... maybe I put the bobbin carriage in wrong? Maybe the needle is bent from using it with stuff clogged in there? Not sure... this is a case for Columbo.
