Hey folks, i have a 5.7 with a 1409 Edelbrok carb that has a rough idle/shake. Engine evens out once i give it the slightest throttle. The engine has new plugs, wires, distributor cap and rotor. I am not really a carb fan or much knowledge about them. What could i start looking at?

Then look at how you have the carb set up.

If it smooths out above idle, there is an issue with the carbs idle circuit. Either a setting, or debris in the carb passages

Will look into the carb and make sure its in working order. Hopefully that takes care of the issue.
