I don't know the difference between them but I think the AV stands for anti-vibe and WB for WoodBoss.

I would think they would take the same bar and chain. Try searching for antivibe/anti-vibe/anti vibe and woodboss. I did find this 028 link which gives some pretty good info.

Thanks that helps alot.

What, pray tell, does a logger cut with an 028? The starter motors on my saws have more power than an 028, lol.
