I change mine to 1/2....

I tried that, but the new husky bar nuts wouldnt go on the poulan bar stud threads.   ???   I didnt check the thread difference of the studs, but figured something was up with that.   
I just said freak it and put the 9/16 back on.

The metric thread Husky nuts won't work on the Poulan studs, despite being 1/2" hex (actually 13mm..............but that's close enough to the 12.7mm that 1/2" actually is to work with a 1/2" or 13mm scrench).

The Poulan studs are 5/16"-18.......same as Homelite E-Z/Super E-Z and XL-101 series saws.  The Poulans have a 9/16" hex, while the Homelites have either a 5/8" or 1/2" hex. 

5/16-18 nuts flanged (with a 1/2" hex) are relatively easy to find, although they're usually serrated.  Smooth faced nuts are the way to go.  Be careful to not buy locknuts.  Do you have a Fastenal near you?  They'll have the nuts you need.

Here's an ebay listing for the right nuts.  They'll have a 1/2" hex.  Most 5/16-18 flange nuts found in an ebay search are either serrated, locknuts (either stover or nylock type), extremely expensive, or a combination thereof...

McCulloch 10-series saw studs are 5/16"-24 with a 1/2" hex.  They won't work on a Poulan or small stud Homelite because of the thread pitch difference.
