Edelbrock carb issue

[737jetdr]

I have determined that my 600 performer Edelbrock carb is causing my problems on my car. It makes a loud hissing,gurgling noise on the right side from the secondaries. anyone happen to know what causes this? Carb is 6 years old but only has about 3000 miles on it. Acts almost like a vacuum leak.

6 yrs and low mileage.

Sounds like it's time for a good cleaning and a rebuild kit.

I found the problem. I have an LD340 intake and it has a small 1/4"threaded hole for what appears to be for the factory choke. I guess whatever I had plugged the hole with years ago came out. instant vacuum leak.
