Problem with motor hesitating

[mas985]

Those symptoms are usually caused by a bad start capacitor. You said you testing it but exactly how did you test it and what where the results? On an ohm meter, a capacitor will appear as a short (0 ohms) initially and then eventually an open (infinite resistance). If it shows any resistance at full charge, it is probably leaking.

Another possibility is the centrifugal switch, assuming your motor has one. If the contacts are dirty, that can cause start issues.

There is a second thread that was started about this that got several replies so I'm going to lock this one.
