Hi there,
I've just spotted your problem in an attempt to track down a capacitor for my Belle MC130 concrete mixer. Mine also starts either way although it can be made to go in the correct direction with a little manual help. Inspection shows that the capacitor bolted to the motor is blown. These sites can help:- http://www.mtmc.co.uk and http://www.belle247.com
Hope thse suggestions help.
