Is there anything wrong with running a bar that's slot is a bit big for the bar studs? I have a heck of a time finding bars that fit my PP330. The one it came with was a cheap Poulan 22" bar thats too much for it, so I modded an old 20" Jonsered bar to fit over the studs, and it worked allright but was still too much for that saw, so I found an old Homelite 16" hardnose that fits good but the slot is too wide. The chain circulates around the bar easily and it sounds good when running it in free air. As long as I have the cover nuts good and tight and the chain properly tensioned I don't see any problem. Bars for this saw seem to be hard to find. The Bailey's bar selector keeps giving me .325 bas but that saw is running 3/8", and the Oregon bars in the catalog don't list that model, although I have a hunch it uses the same bars as the Macs.
