Not a darn thing, you did good and that is what is to be expected. Unless you have an air leak at the small filter, the air should eventually purge out. Any air leak after the fuel lift pump will result in a noticeable fuel leak. A minor air leak before the pump might only show a weeping damp spot if you search very carefully. Might not even spot it. I would inspect the connections of the small filter and any other fuel line connections you might have disturbed.
rough starting after filter changes - 1025r
Recently changed oil and filters (fuel and oil) on 1025r. Subsequently engine starts roughly on first start of the day. Coughs and chugs for 4-5 seconds prior to smoothing out. My sense is air in the fuel system, but I am no expert.
What could I have done during the fuel filter change that might result in this starting symptom?

Mine starts like that for first start of the day without fail. It smooths right out after a couple seconds so I don't worry about it.
Ok then. I will look at the small filter to see if I notice anything and leave things alone otherwise.
For those interested, it was just as Sundancer said. By 3rd or 4th start the air had worked it's way out of the system and we are starting nice and clean as before the filter change.
