Engine Mechanical problem
1962 Mercury Monterey V8 Two Wheel Drive Automatic

1962 Mercury Monterey with a 352 2 barrel carburetor, the engine runs fine when cold, when the engine warms up and the choke opens the engine runs real rough. I have replaced the gasket between the intake manifold and spacer, and between the spacer and the carburetor, this has made no difference. Carburetor was rebuilt in 2003. Have bench set both the automatic choke and the caruretor jets, still has made no diferance...
