Yep if the grease is sucking in then the seal is not sealing correctly.
As for the worm gear puller, I forgot that I think I did already get one and its in my special box.
Its a steel tube that screws onto the worm gear and it has a bolt threaded in the other end that pushes against the crank to pull the grear off without damaging it.
I found this link that has a updated Poulan tool list and it shows the 330 dose use the same puller.

Looks like the part # for the 400, 525 and 655 worm gear puller is diff. from the PP330, etc. Wonder if its because they have longer crankshafts. Other than that the worm gear itself looks similar.
