Hi,
On my 11/72 FJ40, I just swapped out my carb base on my Aisan carb with a vacuum ported unit from SOR. In doing the swap, I noticed the new carb has a vacuum hole in the center that was not on my original base -- see pics below and the associated passage way in the upper body. The gasket between the upper and lower body had a matching hole, so whatever this is, it's now in operation on my rig.
In swapping in the new body, I now have a slight stumbling when I engaged the secondary throttle plate linkage during hard acceleration. This stumble when transitioning to the secondary did not exist before, so I think it has something to do with the new throttle base, but I'm still doing my research.
Thanks as always for any help or insight you can offer.
