78 F-150 now has power climbing hills, thanks to all of your help.
Hey everyone, I have found the problem. The thick gasket under the carb has a crack through the gasket from overtightening, my fault. But thanks to you guys I discovered that I had two vac hoses switched and the fuel cap was not a venting cap also creating a vac in the tank, I also found a fuel line that was rotted and possibly sucking air and I also noticed that the rear end is very worn so I will be rebuilding it soon. Thanks to all of you for your help now it is time for a few cold ones.
