Here's the ms170 which has only one use and he let it set so I did crank seals and replaced hoses/tubes the other is a 180 I rebuilt for a neighbor who survived cancer twice. Free build and I can't even give him his saw bc of the dame issue all are having. I really don't wanna debar any more saws again.

Everyone wants a video I post one, then crickets?
Post #77 is my 180c for OP to post a comparison video
No it won’t- steel bar with not bend and seal against case if flange is stud sticking out-I repair those stud issues once a month from Bubba using Johnson bar on nuts And backing out stud.
but his studs seem to be flush, so that may not be issue.
That's my 180c for a comparison video

Where di
D you obtain that? And ty I can now measure and potentially eliminate flow rate as cause or not the cause
So 5 minutes full throttle should produce about 1oz then
It still ain't letting me see says it's not a valid link

Check pages 17,19,24 and 25 of the guide.
Last tab of each chainsaw model .Has an icon of a cutter with a drop of oil on top .

5 minutes of full throttle ( out of cut ) most probably will produce a fried saw...So 5 minutes full throttle should produce about 1oz then
bar studs. more then likely stripped and pulling out, not enough to visually see them, but it don't take much, even with yer screwdriver you can see its hitting on one of them and not the surface.
and then ^^ that pick shows the bar is hitting the studs as there are witness marks on the stud flange.
Further, these are poly cases right?, they strip out all the damned time, the nuts will still get tight but it will draw the stud out of the case, eventually it will spin free and be a total mess, but in the mean time you're not getting a good seal between the bar and the case, so oil is weeping behind the bar

also the shiny clean spot around the oil groove is a sign of oil bypassing.
its all that or the supply tube (if it has one) is leaking which happens, especially if you've exposed it to alcohol or various gnarly cleaning agents they harden and either crack or get loose
