Help me out, guys. I decided to go down to a 16" bar from an 18" on my 026 (Walkerized). I picked up 3 loops of Oregon chain off of eBay: full chisel 3/8", .050, with the bumper drive links. There is a "72" on the drive links. At the same time, I picked up a 16" Stihl Farmboss laminate bar at the local shop (I was in a hurry), clearly marked 3/8", .050.
So I take it out to the job and everything is cutting great for about 10 cuts. Then things just appear to bind up with the chain not moving through the bar. I switch to a new loop, and the same thing happens.
It appears to be oiling OK. The 18" setup was a GB solid bar with Sabre chain, same specs, which worked fine for years.
Anyone else familiar with this? Is there a chance I got the wrong guage? Is it possible that the tolerances are so tight that the bar rails are expanding? Any ideas?
