Never had automatic oiler trouble yet.
Think that is driven off of pulsating crankcase vacuum with a diaphragm in the old Homelites I own.
I always give the engine a little spin up before I start another cut just to make sure I see oil spitting from the bar tip.
What I like about the old Super XL is that it also has a thumb activated manual oiler, good for kicking in extra oil when cutting sappy stuff like pine.
I remember my dad had a Remington chainsaw from the 50’s that had a manual oiler like that. The saw weighed a ton.
I always thought the motor would have been great for a go cart.
My dad replaced it with a Stihl farm boss in the 1980’s. My older brother still owns that saw. It also was heavier than I like for the majority of the trees I cut down(typically 20” dbh or less).
Bailey’s had the little ECHO arborist limbing saws on sale in their last flyer. These are the saws that only weigh about 9#s. They have the ring on them to attach a rope and pull up into a tree AFTER you climb it.
Now if I need to cut a limb, I use my recipricating saw or my pole saw or hand saw.
