I have a 1984 FJ60, desmogged following the instructions from this site (excellent by the way). I just installed a Trollhole carb, new plugs, cap, rotor and wires. I simply can't make this thing run right. The timing is dead on, decent compression (120 psi). It runs fair when I start it but the warmer it gets the worse it runs. It belches big clouds of black sooty smoke on acceleration and the idle gets very rough. I am only getting 10 inches of Hg vacuum at idle. I have tried testing with carb cleaner and ether with no result. It seems like I must have a huge vacuum leak, but I can't find it. Any ideas?
