Hi all, my carb is acting funny, when the engine is cold it holds idle o.k. but has a very rough idle, once the engine is warmed up the truck idles very high (I do not have a rpm gauge on the truck to know the rpm speed is) and is a smooth idle. I recentaly had a rebuilt motor installed (22r) and it runs and sound fine otherwise, no knocking, pinging, or valve noise. I have tried spraying some carb cleaner into the carb and run some fuel cleaner into the gas tank both with no results or improvements. The exhaust is not smoky but does throw out some black like stuff (carbon?). Any help on what the problem might be, and thanks in advance.

PS it is the original carb that came with the truck when I bought it new in 85'.
