That sounds like you might have a valve problem or worse. :( Does the carb suck any air at all?

Fuel filters don't always fill completely. Mine never has on my Deere's Kohler engine. So I would not worry about that. You can download a service manual for the L-Series here that might cover your unit:

Curious, how many hours does it have on it?
