My brother got me a uses 290 a few months back. Starts up and runs but after cutting through some bigger logs today I checked the fuel and oil and the fuel was 3/4 empty while the oil was around 1/2. I cleaned the bar like crazy when I got it and it was spitting oil when I cut some dead pine and oak in April. Didn't look to see if I was still spitting steady tonight. I'm sure I could use a good sharp chain seeing this is the one as is that was on the saw. Uploaded a few pics for reference. Burnt chain? Any other ideas or what I can look at?
