bought an Aisan carb that was supposed to be for my 1975 FJ40 2F. Now I'm not so sure. How do I tell what the ^%$& it is. It says Aisan on it and is marked 180 - 3j15 on the top but it does not look like any of the carbs shown on SOR. Am I screwed?
Part of that number is the date code. 3j15 means it was made on October 15th on some year ending in 3. It's up to you to determine whether that's 63, 73 or 83. It's probably not 63. 83 would have a lot more vacuum ports than the 73 one would.

is that the large tube in the next to last picture? If I use this carb on my de-smogged 76 2F can I just close off that tube?
Sure, plug it, and then get the rest of your linkage pieces too, otherwise the acceleration circut will not work..
