I recently bought a stihl ms 660 magnum. I have been having problems with the chain oiler. I burned up a 32" bar and 2 chains after turning up the oiler as far as it would go. I tried thinning out the oil and opening up the oil hole in the bar. After I run through a tank of fuel there is at least a half of tank of oil left. I even went so far as to purchase a woodsman pro 36" bar and .063 with a 404 and it still heats up. any ideas?
