I used (I mean really used, not just trimming) my 361 for the first time over the weekend. It doesn't seem like it is oiling enough. I have a 20" Rolomatic bar, 20" Stihl full skip semi-chisel chain. Both are brand new. The oiler adjustment screw is maxed. It is definitely using oil...the area around the sprocket has oily sawdust and I'm using about a tank of oil per tank of fuel...so it's pumping it... The bar groove is getting gummed up with debris...if I run a small screw driver down the bar a bunch of oily crud comes out. After about 10-15 minutes of bucking some black locust the chain was hot enough to smoke off the oil. Any thoughts?
