Noticed this while cleaning my saw this evening. Anything to be concerned about? Also, the drum does not seem to be "square".....as in, the outer rim is just slightly oblong, and if I lay it flat on top of my bar, it does not sit flush in 2 spots. Maybe it's supposed to be like that, or maybe I can use this as an excuse to go ahead and get a power mate rim set and try a few different size rims.
Thanks for any input
