For a while ive been chasing oiling issues with the 6100. It just never seemed to oil enough, and the bar and chain would get too hot. I always assumed it was the bar or oiler(clogged oil hole, not lining up correctly, pinched rail, tank vent, rakers too high etc) because we got a new Carlton chain after I messed up the stock safety chain. Well after issues with quality and fit of my cheapo 18" bar I just gave up and traded the chain I got for that for a new Oregon full chisel in 20" but dont recall the product number. All the oiling issues are gone. Has anyone had a similar experience? Is there a design difference that allows the Oregon to pull more oil around the bar? I havent taken the chain back off to compare drive links and other little differences. When I do, Ill take pics. Just was an interesting experience and though I would share.
