1985 Land Cruiser fuel/emissions problem Seems to have vacuum issues. Replaced intake exhaust gasket, carburetor rebuilt, new fuel pump, Runs fine at times but starts to loose power to where I have to bury my foot in the accelerator just to keep it running.

Check the fuel filter.
Why vacuum issues? If you put a vacuum gauge on it and the vacuum is low, you may have a plugged eshaust, for one thing.
