"Why do you wanna [MG] when you gotta horse?"
-- Chico Marx
But seriously, folks, would I be correct in guessing that the Weber is a
two-barrel downdraft, with each barrel serving 2 cylinders? In that case it
seems pretty clear that you have a clogged jet. This is not all that
surprising -- when the fuel level gets low it tends to suck up more of the
crud at the bottom of the tank. I have no idea how you would go about
cleaning out your Weber (SUs, sure...), but I imagine it could be done. Then
you might want to replace the fuel filter.
