So I flush from the small cog side and wait until it runs clear out the back/inside?
The flushing won't flush in grit?
then let dry and drip in the Tenacious or other oil?
This is too simple, there has got to be a catch some where

The only catch is that freewheels are originally packed with a light grease. By replacing it with an oil you will need to lube it more frequently. And since the oil doesn't dampen any sound it will probably be a tad bit louder. In any case the best way is to flood it from the back like everyone is pointing out, let the wd-40 evaporate and then lube.
