Thermoquad running rich

I ran thermoquads for years, and they were excellent carburetors. Back when we could by strip kits, I would tune the carb to perfectly compliment the 440 in my Charger. Since your engine is new, do what the others have said and put some miles on that dude. Before taking it on a drive, do what K.O. said and run the engine & then let it sit and look for any spillage into the throats of the carb. If none, then go for a drive. Does it start ok, or do you have to crank it a long time? Does the choke fully come off when the engine is warm? Do you have to keep it revved up while it is cold to keep it running? When properly set, you should be able to pump it once and hold the throttle about 1/2 way down and it should fire right up and keep running.
It starts good even when cold. If it hasn't been ran in a couple days I have to pump the gas a few times. The choke works good its fully opens and when warm and closes when cold. It will fire right off and idle i don't have to feather the gas or anything to keep it running. I can get in it and pump the gas a couple times turn the key and it fires up. And I can walk away and it will purr like a kitten lol.
