From your description your choke is set up as a 120-cycle trap using the capacitor to create a resonant circuit.

Two choices here. Leave it out if there's no hum, or replace it. I wouldn't leave the old one in place.

Although its not your chassis you can see an example of the usage on Page 13 of the Rider info on the Model 90
