Honda HR216HXA carb question

Picked up this classic. Looks like it needs a new carb. I believe it has the GXV140 engine; that's what the manual says. In searching for aftermarket carbs, I see the style pictured below; description says it fits the HR215. But it has that little attachment thing on it which mine doesn't. Otherwise, the rest of the unit looks like mine; ie, linkage connectors, etc. Would this one work on place of the original? And I am most curious as to what that attachment does. Anybody know?

suggestion: purchase Honda OEM parts.

First the easy bit.
The thing on the side is a fuel tap.
If you see the same thing with a bowl on the bottom that is a sediment filter usually only found on stationary engines.

Now as the saying goes, " A fool & his money are soon parted" and dads favourite "he who buys cheap pays thrice "

Because of the flood of counterfeit parts pouring out of China, Honda has dropped their parts price to near cost.
So get the RIGHT carb from a Honda dealer and you will know it WORKS .

Buying some thing off the web from some one who does not know anything about the part , so has listed it incorrectly is a stupid thing to do.
You have no idea who you are buying from or even if you are buying a part that has been tested & works or buying reject defective parts purchased as scrap metal then sold off to cheapskates.

There is a big difference between:-
"fits" , it will bolt up and the control wires will hook up
or
OEM = came out of the same factory, might be good or might be scrap
and
Guaranteed certified replacement part.

About 1/4 of what comes through the gate is stuff that an owner has tried to fix with cheap parts bought off ebay or amazon that were defective.

HR214: GXV120
HR215: GXV140
HR216: GXV160

And that is a fuel shutoff and sediment bowl . . . definitely present on the GXV140 on my HR215, not sure about the HR216 . . .

The carb shown is for a Lifan engine ( honda knock off ).
There is no sediment bowl on it, just the on off tap, usually fitted with a neoprene seal that goes to mus in 1 to 2 years and totally clogs up the carb.

I was talking about my GXV140 carb, which looks like that. 30 years later, seals are still fine, and I believe it was Honda that had said 'sediment bowl' in a manual I read, but I can't find it now, so ???

And don't care about craptastic Chinese parts . . . there are typically far bigger issues than seals . . .

The identical looking Honda seal is made from n-bunya rubber and lasts for decades.

HR216 was a typo; its an HR215KHXA with a GXV140. The fuel shutoff/sediment carb is described as a replacement for an HR215 & GXV140. Yet mine doesn't have the shutoff/sediment bowl; it looks like the one below. I'm asking whether the shutoff/sediment unit would work/fit on my mower, OEM or otherwise, and at this point, that's the only info I am seeking here. What do you think( I think it would work)? ... & thanks so much for helping me.

The shut off valve is just that, a tap.
Will not make nits knacker of difference to the operation of the engine.
Only problem will be fitting the fuel hose if the inlet is at a different angle or different position.

It should work for now. As previously mentioned if the seal is cheap neoprene it will fail in a season or less
So the question is "do you feel lucky" ?

A bigger question is why not just clean/rebuild what you have, instead of risking 3rd world crap? If what you have is an actual Honda carb, you will be hard pressed to do better . . . As far as fit, the GXV engines are all pretty much the same, so unless something on yours interferes mechanically with the shutoff, it should work fine . . . as noted, the HR215 (at least earlier ones) were stock with the carb with the shutoff, so either it was changed on later K variants, or someone downgraded it for you already.
