Thanks to all for the suggestions. I ended up using a battery powered pump. I wish I had bought one of the vacuum rigs, but, this worked well enough. I only seemed to get 3 quarts out, so, I flushed with 3 quarts, sucked it out again and filled it back up. The dip stick shows clean oil now.
The trick as had been said is to get the oil hot enough. I turned the engine on and waited for the temperature gauge to get up to about 170 or so.
