Then leave it like it is. You asked for help and were given it. Now you say "but this but that". It takes 5 minutes to make air fuel adjustments and idle adjustments to a carburetor. Get it up to temp good when it starts running badly. Set the parking brake and block the drive wheels if it's an automatic. Hook your vacuum gauge up to a manifold port on the carburetor and start it up and drop it in drive. Now adjust the air fuel screws to achieve the highest vacuum reading. If it still runs rough, put your timing light on it and see where your initial timing is. Low initial timing is one of the biggest culprits for a rough running engine. After you get those adjustments done, if it still runs rough, it may need some attention to the carburetor.
