Yeah, this is what I've been doing: I purge the kegs with co2 then hook up the line from the bucket spigot to the bevport. Then I hook up a gas port with no line, this lets the air out as it fills up. I found out why it was running so slow, there was a wee bit of yeast cake that floated and clogged the line. The second keg I racked went much faster since it had been in secondary for 3 weeks.
