Just built a 350 with about a 0.500 lift on the cam, edelbrock preformer intake, 2.02 1.60 iron heads and I'm having a problem with the carb. Bought a 600 cfm edelbrock with an electric choke and vacuum secondaries. I'm having some trouble at idle...sometimes it idles kinda high. Also I think its running pretty rich. I was thinking that I need new metering rods but I'm not sure. Does anyone have any ideas on how to tune the carb so I can have a nice idle and so that it won't run so rich?? Thanks

 

I never liked those carters. A common problem with them from new is bad throttle shaft bushings. See if your throttle shaft has any movment. Could be drawing air.

 

Is there anybody that makes new bushings or do you just recommend a different carb? Maybe a Holley?

 

I would check them first. If they are bad you should be able to move the throttle up and down and around. And you can get them rebushed. It usualy takes a tool to ream and resized bushings though.

 

So its probably not the metering rods or jets that are causing the high/rich idle?
