Edelbrock 1406 whistling

How do I know? Can I unplug it and tell? My other rod has a manual choke, so I'm a stranger to these electric jobbies...what makes me curious is that the day I started the car, and this whistling started, the choke was WFO until I kicked the gas down....it had never done that before.

Take the air-cleaner off.
When the car is warm is the choke fully opened or closed ?

Another thing you can do for test purposes, is disconect the choke wire and wire the choke open. This is for test purposes only.

I dont even run a choke here in Cal. Actually that is the first thing I remove on these carbs.
