I'm working on a 77 FJ40, everything stock 2F engine. This cruiser has under gone a restoration for the last couple of years, so it running for the first time in a while. Everything has been gone thru and carb was rebuilt. I pull the choke all the way out and it starts good. Let it warm up a bit and start pushing the choke in. As soon as the butterfly valve starts to move, the idle drops and the engine dies. I have put thread sealant on all fittings in the intake manifold, tightened the intake manifold bolts, remove carb and cleaned all the mounting surfaces. I have had someone who knows a lot more about carb adjustments do the adjustments and he has said the adjustments are where the should be. I checked the vacuum at full choke and its 16.5. Can't check any lower then that cause the engine dies. I'm stuck on what to look at next.
