I have a Stihl MS290 "Farm Boss" saw. Bought it a few years ago and used it very occasionally keeping up the property. This year I've cut down a number of decent sized trees on my lot - and I thought that the bar oiler had been working ok - I saw a small amount of oil on the bar - and the oil resevoir was always going down (had to fill it on every tankful of gas).
On Saturday I notice that the saw is cutting really bad - right after I sharpened the chain. It's just spitting out sawdust. I check the chain - it's sharp. And there's smoke coming out when I'm cutting - and the bar is looking a little burned. I check the bar - and it's dry. But the oil appears to be going somewhere.
Is the oiler pump a diaphragm? Because I also noticed right about the same time that saw was getting harder to start. I'm thinking that the saw has been burning up the oil instead of sending it to the bar - because maybe the diaphragm in the pump is bad?
How hard are these to replace?
I was halfway thru a tree when this happened and had to keep going and get it down. I still have lot of cutting to do so I need to get it up and working again.
