 I can not seem to solder a banana jack correctly, I end up with solder
at the top 20% of the jack rather than completely into the jack, down the wire...suggestions please.
Does the jack need to be vented, maybe air locked preventing flow?
thanks....

 Maybe if you posted a picture of the jack we could see what you are up against .

 Fully tin the speaker wire first.
Get an iron with enough wattage to heat the jack quickly.
add a small amount of solder when you do the final assembly.

Compared to the actual contact the banana plug is making on the binding post, even 20% solder coverage of the wire to the banana will be a far better contact than the banana to the post. Spade lugs give a lower loss connection.

 Does it have a coating? Gold etc..

Maybe file off the coating and get to the copper.

Picture would help.

 I too have found that filing off the outer coating down to the copper is very effective for many speaker binding posts.
