Maybe it's a "bigger" capacitor?

There's no mention on the package of how big the cap is, but physically,
the combination unit is far beefier than the OEM unit. So I dunno...

Do you think it could be as simple as the compressor just needed a
"beefier" cap?

Why would it need a beefier cap?

A more-capacitance cap would have a lower impedance and allow more
current to flow. More current in a motor means more torque.

There is still the possibility that the original cap is defective. That
the parts-place check did not measure capacitance, or if it did, it
wrongly concluded that the capacitance that it measured was the needed
value.
