OK I have a question about this install. I have the C clip off, and the bowl cover off. I'm supposed to pull down on the push rod and disconnect from the plastic arm. It doesn't say how. If I could just see the underside, i'm sure it would be obvious, but I have never seen it out. It's plastic, so no room for a learning mistake! I've studied it for a bit but just not sure. Hoping for a quick pointer as i'm in the middle of the swap right now! Just taking a little forum break!
