Maybe it's normal, but my Husqvarna 357XP leaks bar oil like crazy. There's a little adjuster screw on the bottom to determine the amount of oil that gets fed to the chain and the greatest concentration of fresh oil seems to be around that screw. I haven't fiddled with it much and it's not been abused so I'm kinda at a loss as to why this thing is leaking. Might not even be from that screw, could be from elsewhere and just pooling there. Anyone else have such a leaky saw? What would be causing this? Remedies?
