Ford F-250 Repair Question
I'm not familiar with your car but the correct way is to first make sure your timing is correct. Warm up the car to operating temperature. Turn the car off. Disconnect the vacuum hose from the distributor , if it has one, and plug the hose. Connect a vacuum gauge with a tee fitting to a vacuum line. Turn the idle mixture screw on the carburetor all the way in and back it out 2 turns. Start the car and adjust the screw until you have the highest steady vacuum reading possible. it should be about 20 inches of vacuum.
