I've got a question about the supposed gasket that remains once you've pulled your carb off. 81 fj40 with all the smog gear. In this post here Jim C talks about a gasket not being necessary. I called the dealer and the guy told me the only thing he had was the tray / block combo, which would also backup Jim C that the thin gaskets are aftermarket (like in the ones from SOR in the post referenced above). The tray / block combo was 90 bucks -ish. Since it doesn't appear that there really is a thin gasket on top that comes off, I won't need one My question is, do I need to put anything on top of this surface before I seat the carb on it upon re-install? Here's a pic of what I'm talking about: pic Thanks in advance.
