Jake, the anti-vibes on these are not like their 2xx series cousins, and require replacement from time to time. That and the aforementioned intake is about the only thing troublesome on these. They are a fairly mechanic friendly saw to work on. Mods can be done just as much or little as the Pro saws do. As far as parts go, was able to do a one stop shop at HL Supply for everything needed to rebuild one of these saws. As said before the air dam/plastic intake can be repaired by one of numerous ways if you have trouble with it. HL Supply has good rubber intake and impulse parts for this and I recommend changing them. Other than that, have fun with your build and let us know how your doing with it. SS
