Any idea why my excavator stalls when I use the boom or stick after fixing the swivel joint?

I've got a Caterpillar 315L excavator that sat for years before I got it. I went through it pretty hard, rebuilt cylinders, got it running decently, then had tracking issues. Ended up rebuilding the swivel joint, and that actually fixed the tracking problem. The machine now tracks strongly and feels normal there.

But now I've got a new issue. Whenever I move the boom or stick and deadhead it, the engine bogs hard and sometimes stalls completely. It runs fine at idle and light movements, but as soon as it's under load, it just can't handle it.
