Any info on how to replace this set screw? One side of the slot broke a few years back and this saw leaks bar oil like crazy in the case. It’s probably staying slightly open due to the inability to completely close.

If it sticks down far enough (after you remove it) you can easily slot it with a dremel and small cut off wheel.

Not sure how one of those could get damaged, it's not something you really ever need to mess with once you have it set to meet your needs.......

Same as I’ve done on carb screws I guess. New slots are easy to make though this screw may not have enough meat to do so. I must have heavy handed it with a larger slotted screwdriver when it snapped off. That’s unlike me.

Now, when you say “never mess with” that would be my preference but ever since I’ve had this saw bar oil would be leaking heavily in the case. Could be the Walmart super tech or the oil manifold is faulty. This is with the set screw closed too on a hot saw.

That has nothing to do with bar oil leaking, it just sets how far the oil pump piston can travel.
There are several things that can make bar oil leak. Tank, or pump hose connections, pressure building up in the tank, could include a bad tank vent but normally they are vented one way to let air in. Now there is also a little but that will naturally drain out of the bar and the case from using the saw, but it shouldn't amount to much.

I would say at times half the tank’s volume would spill out. Not often at all. Moreso it’s like 2-3 ounces. So it appears I have another issue at hand then as you surmise. I’ll have to clean it up and closely monitor the leak. I was able to close the set screw completely and I refilled the tank leaving it on my work bench on top of some towels. I also had removed a generous amount of oil soaked dust.

You have other issues. The set screw doesn't limit oil flow, it limits the oil pump piston travel. A few ounce puddle could be normal, but I'd suspect you have other issues if your pushing half a tank out. Before storage try popping open the oil tank cap to let it vent with the storage area. Won't really help much if it's being stored outdoors with temp swings, but if it's in a temp controlled area it will most likely solve the issue.

I have a Husky 385 XP that has a wire that goes through the adjusting oiler screw, well the screw broke and the only remedy now is to replace the oiler unit. Gonna be a shitshow !
