▷▷ 2021 ▷ How to adjust a Dodge carburetor

2 julio, 2021

The standard size carburettors used by Dodge are typically the two-barrel style with two adjusting screws to help fine-tune the carburetor. They have a simple design that allows you to make adjustments to your carb fairly easily. Adjusting your Dodge carb should only take about 30 minutes and will save you a lot of money in labor costs. It will also help you save some money by using less fuel, as your engine burns gas more efficiently because the carburetor is properly adjusted.

Remove the air filter from the top of the Dodge carburetor by removing the wing nut from the air filter by hand and setting it aside. Locate the two adjusting screws on the lower cylinder of your carburetor. The upper adjustment screw is the idle mix screw, while the lower is the idle speed adjustment.

Start the Dodge engine and let it idle until the engine warms up and the choke valve in the carburetor cylinder is open. Locate the vacuum hose that is connected to the vacuum outlet port on the carburetor barrel. Remove the vacuum hose and connect the tachometer to the vacuum outlet port.

Turn the idle mix screw clockwise until you feel the screw stop at the bottom and then turn the screw counterclockwise two full 360-degree turns. Repeat this process with the idle adjusting screw.

Check the tachometer and read the rpm level. A properly adjusted idle speed should read about 850 rpm. Turn the idle speed adjusting screw with a screwdriver until the tachometer reads 850 rpm. Turn the idle mixture screw clockwise a quarter turn to tip the fuel mixture. Check the rpm again on the tachometer and turn the idle speed adjusting screw until it returns to 850.

Continue this process until the idle mixture is low enough that the engine almost stops, then turn the idle mixture screw 1/4 turn counterclockwise and check the tachometer. Adjust the idle screw once more to 850 rpm. Remove the tachometer from the vacuum outlet port and reconnect the vacuum hose. Replace the air filter on top of the carburetor and secure with the wing nut. Turn off the engine and remove your tools.
