Common rule of thumb, you can tell when a capacitor is bad but you can’t tell if it’s good.
IOW a meter isn’t always the answer and caps are so inexpensive, replace it. That’s a common size.
You could go up a little on the capacitance but not down. A 440 VAC rating would be fine also. That’s a run capacitor.
Any AC supply house would have the cap.

A true start cap would be in the 200 mfd range (177-217 for instance) depending on the HP of the motor.

Except they are almost all too big (dimensions).

That's what I figured. But then this 47 uF 200v cap in the chipper motor makes no sense, unless it's a case of serious skimping.
