Installing a new carburetor is not a very difficult project. You don't need many tools and aside from some adjustments it does not take very long. The Edelbrock carburetor we bought comes pretty much ready to go. A few things you may want to consider ahead of time may be the fuel lines and pcv lines. If you are installing a new type or brand of carburetor the location of the lines may be different. So it is always a good idea to get a few feet of 3/8 or 5/16 inch fuel lines just incase. Having a new fuel filter is also something you may want to pick up. The other thing to consider is that if you need different length lines coming off the fuel pump then you do not want them coming in contact with any heat sources (valve covers, headers...etc), so grab some plastic ties if you need to keep the fuel lines out of the way.

Removing the old carburetor is pretty simple, there should not be many things to disconnect. Typically you have the vacuum advance, fuel line, pcv line and the hot lead to the electric choke (if present). Once you have removed the lines simply loosen the bolts (½ inch in this case) and remove the old carburetor. Be careful not to get any debris into the intake. If the old gasket is stuck to the base then plug up the intake with some clean shop rags and gently scrap the gasket off with a screwdriver and clean it up. Now you just put the new gasket on and mount the new carburetor. Reconnect the lines and you should be ready to try it out.

After adjusting the idle screw and idle mixture screws there was no improvement. We figured there must be a vacuum leak so while it was running we sprayed some starting fluid near the carburetor to see if there was any higher idle spots. There were none so we checked for leaks in the other lines. Nothing. Eventually we pulled off the power to the electric choke, started it, there was no racing, then we reconnected the line and started it. The choke must have reset because the idle was much lower and there were no problems after that.
