Eric, I plan on lubing my blower soon, and since it's a pain to get to, I will probably replace the brushes while I'm at it. I'm told sewing machine oil is the way to go. As for the brushes from carbonbrush.com, do you have a p/n you used to order them or did you order them by size measurements? Please give me info so I can order some for myself and have them before I pull everything apart. Thanks in advance.
