It is called a "Thermo sensor (valve)" I got that info from the Zuk service Manual here is a link to it

Wait, isn't the function of that valve to open & close the flapper for the (usually long gone) hot air intake?
Don't see many carbed engines that still have them functional, & if yours isn't there's no point in replacing that valve. You could just cap it & the vacuum nipple that feeds it... unless it has some other function?

honestly, I dont even know what the rest of that system LOOKS like, since I'm not super familiar with samurais yet.   if I can just cap it off and be done with it, SUPER.

Well, the hot air intake on sammys used a tube that runs from a T on the intake... one side runs into the fender (main air intake) & the other sorta looks like a clothes dryer vent hose (except ~3" diameter) that ran over to the heat shield on the exhaust manifold. If that tube isn't there then your hot air intake is gone.

I'm not 100% certain that's what that valve does... but I think it is. Here's how to tell: Follow the vacuum lines, one should go to the intake (or carb base) & the other will go to a vacuum valve at the T on the intake tube. If one goes there... then that's what it is. I have a Tracker, not a sammy so I can't just go look, but I've had several carbed vehicles that had a similar setup... & not 1 of them ever had a working hot air intake. Maybe one of the sammy guys will chime in & confirm or correct me.

If you look at the link i sent you, you can see the things that fuzzy1 is talking about it is a online viewable pdf file you don't have to download anything just wait for the page to load then scroll to the section you want to look at.

That is exactly what it does - it senses the intake air temp and uses engine vaccum to open/close a flap in the T in the intake tube.
