I have a husqvarna 51 chainsaw that I have been working on. I have it running pretty good now but I have exsessive bar oil. I can see oil spraying off the end of the bar when the saw is running, and when I turn the saw off, I can come back to it a while later and there will be a pool of bar oil onder it. I have read about an adjustment screw, but this model doesnt seem to have one. I pulled the side cover off yesterday and cleaned all the oil off, and then I turned the crank by hand 2 or 3 rotations and it pushed a drop or 2 of oil out of the oiler hole. Is this normal for so much oil to come out? I am not sure if the pool of oil under thesaw is from another leak, or if its due to the fact that so much oil comes out while the saw is being used, that all the excess makes its way out after the saw is shut down. I have left the cover off over night and had everything clean so hopefully I can see where the oil is coming from, or see if there is any oil at all since I didnt run the saw. If it is over oiling, what can cause this since there is no adjustment scew?
