Tips on Removing and Replacing Your Carburetor
One of the most helpful thing you can do while removing your carburetor is to get your digital camera out and take pictures of every step you take, then put the pictures on your computer for later viewing. Take pictures from every angle including several close ups. I do this on every carburetor I take apart on the bench. Any time I have a question, I refer backto the pictures.
Lacking a digital camera, make a drawing as accurate as possible that will show where things go.
Mark your vacuum lines with masking tape, labeling each one.
Stuff a rag, or towel down the carburetor throat to prevent you from dropping anything down the carburetor. You don't want to be forced to remove the manifold, or heads looking for that small screw.
When removing bolts and screws, start them back into the base unit so you have the correct size bolt later.
Do yourself a favor and use flared nut wrenches to remove the fuel line.
After the carburetor is removed, stuff the manifold opening with something to keep foreign material out of the manifold.
Remove the base gasket from the manifold. Keep in order to match it up with the new gasket. There can be very suttel differences in some carburetor gaskets.
Clean the old gasket off of the manifold. Be careful what you use so that you don't damage the manifold metal while scraping. A dremmel tool works good here.
If your vehicle has been sitting for a year or more, drain the gas tank. The gas is probably stagnant and will ruin an otherwise good carburetor rebuild. Better yet would be to remove the gas tank and have it boiled out.
Change any fuel filters before running the new carburetor.
When bolting the carburetor back to the manifold, don't over tighten, or you may warp the carburetor base. Don't tighten more than 10 lbs. That isn't very much.
In summary mark, map, label and be patient. You will have a smooth carburetor job.
