Carb heat shield non-existent on non-USA (1 Viewer)

[algeeba]

So why is it that, for example, 2Fs from the Middle East don't have a carb heat shield, no carb fan, no fuel-return and apparently, I'm assuming, do not have problems restarting after a hot drive?

I have a de-smogged '78 FJ40 w/stock exhaust manifold and I need the carb fan to help restart after a drive. I keep thinking that maybe the carb heat shield is actually trapping hot air underneath the carb longer than it needs to. I would think a de-smogged US 2F would be like a non-USA 2F.

Could someone please explain to me what is going on?

Thanks in advance.

One thing they do have is a better multiple bladed fan. Maybe that eliminates the need for the heat shield and carb fan...

Hmmmm. How many extra blades do they have? Do you know if it's the same setup using a fan clutch or is it direct?
