Any advice on what size capacitor to buy and try ?


IIRC about 2.2uF 450V DC or 250v AC is the approved sort of size. For
a sport of one horsepower motor thing.

You'll find these in pre-loved (skip grade) central heating circulators
(pumps)

Although the capacitor might well be the reason why the pump is in the
skip ...
