Cavalier uss 10-80 not cooling

[dwbarg]

I got this machine the other day and it seemed like it was blowing cold air.  The machine had a hang up in the vending mechanism so I removed it to repair.  The machine ran all night and was cool inside, but the front bulb was iced.  Anyway the machine was nasty from sodas busting in it so I moved the evaporator and cleaned the floor and put the evaporator back in.  Now it won't cool.  All fans and compressor seem to be running.  Where do I start?  Thanks

look for where you maybe crimped a cooling line to start with.

I didn't find any kinks in the lines.  So whats next...check for leaks and add freon?
