Clogged passageway? Need to get some small picking tools to clean everything up.
 
i would take it apart and clean it up. see if that doesn't do the trick. could just be really gunked up
 
Air compressor and a blow gun works better
.
 
Yup. Looks like a lot of very fine flour like dust on your felling dogs, usually from a dull chain. I'd bet you need to pop off your bar, blow off and brush off the oil channels, clean around the clutch and in all the grooves of the bar and oiling passages, and you'll be good as new.
 
Never had an issue with the chain oil. But I maintain it often. I've always wondered if you could tell the oil feed was plugged up. That is before the chain smokes. I have the oil feed wide open. More is better. With every fuel fill, I fill the oil. The oil is about half empty. I pull bar, often and clean everything.
 
I have this great tool

Plus don't forget to sharpen the chain so you don't get saw dust.

A sharp chain ... ;)
 
and especially when ripping soft wood such as cedar. sometimes 6 inch+ strings.
 
Ripping. I get them a few inches long with a sharp blade.
 
Never cut maple but like Tadmaz said above they get long in softwood.
 
50yrs ago all we had was a mini mac 6 for cutting fireplace wood. Saw a lot of dust coming from that thing. Somehow the idea of a sharp chain wasn't very important. Last time I used it, it wouldn't cut, at all. Actually, it threw sparks. Just depends on where you're at in life. That was a long time ago. A lot has changed, lives change, people move on. Now equipment around here runs like a swiss watch, and cuts like a btch. Ribbons it is or it's shut down and tended to. I like things a lot better now.

I'm a fan of big old ribbons myself. That's where I like my chains to live, but big chips flying at a minimum. I've had more than person point out and comment on the ribbons shooting from under my saw while I was bucking.

OP has a very dull chain to be able to create the fine dust that seems to be all over that saw.
