Chevy 350 Engine -- Carburetor Installation Guide

We all know that carburetor is fitted in a car to blend its fuel and petrol in appropriate proportion. But while incorporating carburetor in Chevy 350 engine, there are certain steps that one must follow.

Before you install carburetor, it is important that you go through the warranty. Once you install it in your Chevy 350 engine, then it will be considered as your assent to all terms mentioned in the warranty. Thereafter, separate the air cleaner assembly. Take in notice all the loose, swollen or cracked hoses, diaphragms, heat riser tubes and replace them with the new one.

It is good if you make a rough diagram of the carburetor's placement. Mark all the hoses and wires as A, B or C etc. now this drawing with the hose routing diagram under the hood or in the manual of your vehicle. If both are not same, then the professional help is recommended. You have to check it carefully as mistake can be anywhere.

You need to disengage Choke heat tube, vacuum horses, fuel line, P.C.V. hose and transmission kickdown linkage. You will also have to disconnect other parts also such as throttle linkage, throttle return spring and electrical plugs and wires. Be sure that you are using special "flare nut" wrenches or you might damage the fuel line.

To remove the carburetor and flange basket, loose the hold-down bolts or nuts. Make sure that it is similar to the earlier one. If there are differences between them, you should call the manufacturer or the dealer. If you find it wrong, then do not install it.

Always use the correct base gasket, and if it is not included then you can purchase it at the auto parts store. Do not forget to put cloth into the intake manifold opening while doing this. It is done to prevent dirt or chips from getting entered into your Chevy 350 engine.

Now put off the cloth from the manifold but make it sure that the dirt has not entered the manifold. After that, you can install the base gasket, and shim if you find it needed. You need to be careful about how you put it on.

You can now set the carburetor at its place but do not fasten it. Before that, you need to check that the unit had not received any damages in shipping. For that, you should open the throttle linkage fully and then close it again. Check all vacuum and fuel hoses to see if there is any crack. If you find everything finer then, you can tight it. All the small pipes of the on the carburetor, which do not have a attached hose must be cap off.

Always use 1" wrench for the secure holding of the fuel inlet, while you are fastening the fuel line to a Rochester carburetor.

You will have to ensure that there must not be any space so that dirt cannot get inside the unit through the fuel line at all.

Keep in mind that while you are staring your Chevy 350 engine, you apply parking place so as to block the wheels. Never stand in front of the vehicle and when it starts, look for leakage. If any, stop the engine and do its repair. If not, then set the idle speed of your vehicle, and do as directed by manufacturer, to adjust idle mixture through the lean drop method.
