Hello !
I have a set of rebuilt carbs on my '68 311. Seller claimed they were rebuilt by Keith Williams and I have no reason not to believe that. I thought I had everything close to dialed-in, though with a plug check it's running a tiny bit rich. The main issue I am having that when it is warmed up, it will sit and idle nicely at 600 RPMs - but after about a minute, it will begin to creep down and stumble around 400 RPMs until I blip the gas. It's almost as it becomes fuel starved. I've verified valves/timing are in spec. I've used the "magic number" to set mixture. Can I get suggestions on where to look next? Lean out mixture? Float height? Fuel Pump? Any suggestions would be appreciated.

With it idling at 600 try leaning them out a little. If the idle speed picks up then you were a little rich.It sounds like loading up from being rich.
