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?

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.

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.
Did you pull and clean the pilot jet and needle as well? The only time I have not gotten a carb back to 100% with cleaning, a kit (sometimes) and adjustment was one of these, and 20+ years in ethanol fuel had caused the pilot jet to shrink and the engine surged. Replaced that, and perfect for the last 10 and still gping strong.
I don't as much have an objection to offshore mystery parts as I do unneccessary parts, and I would wager that at least 95% of carb replacements are not needed . . .
Also note that the issue is not so much where it is made, but for/by who . . . Honda can get stuff from where ever it wants, applies it's QC and backs the part. ChinFatCo's $9 carbs you are lucky to find the mfg the next day (or ever) and QC is a maybe, and nobody backs it . . .you are 0n your own before the part even arrives.
Oh, and I find my HR215 to be worth more $$$ than any of the junk sold today . . . Can't find anything even close for under $1000 . . . rebuilt mine (engine included) for about $200, and should go another 30 years . . . a lot depends on how abused it has been though, that's for certain . . .
Good points all ... yeah cleaned the jet & needle too. The jet on this carb screws in on top of the emulsion tube & is brass. Is that what you say had shrunk?

Nope - the black plastic pilot jet that presses into the top of the carb . . #24 in the parts list linked in the last post.
Ok, I see it now. BTW, I think you nailed it as to why some HR215's have the shutoff version but others don't. It appears to be that Honda changed things, for whatever reason, on later models. Come to think of it, I haven't seen any engines (GCV160's &190's) with the shutoff in the last, say 10-15 years.
Usually the cut off is fitted to the commercial engines because they bounce around in their trailers and tend to flood during transist.
Also commercial operators are nowhere near as price sensitive as the domestic market.
Cut off valve with sediment filter is generally found on stationary engines because the sediment trap would not work with the mower bouncing around on a lawn.
There is no problem with Chinese made parts that have ben made in a quality controlled factory,
Honda has 11 factories in China, All of the Honda engine we get down here come from China , as does most of the small Briggs & Kohlers.
And yes the factories in China buy in carburettors from other factories in China.
The difference is what gets put into a bag with Honda on it has been quality controlled , inspected and passed.
The scrap that gets rejected ends up being sold on Ebay & Amazon.
Thus the bad carburettors with problems that were made by the factory that supplies carburettors to Honda end up being sold as OEM & fitting x,y & z.
All of which is true, what gets omitted from the description is the carburettor was one Honda rejected as being substandard .
Having said that some will be good, they are simply over production.
The problem is there is no way of telling till they get fitted and the engine still dose not work right , so the owner rips into the engine , oft doing more damage doing so thinking that it can not be the carb because it is brand new from an OEM supplier.
I see these all the time, they come through the gate, the owners having thrown a lot of money at them replacing all sorts of things when the problem is a faulty carb and the original problem was a dirty carb that was not cleaned properly which is a lot harder than many would expect, some taking several hours in the ultrasonic cleaner with very agressive cleaning solutions.
I am an independent service technician & fit CHINESE parts , however they are bought through real wholesalers who have a real warehouses, real reps and cover them with real warranties as they are quality controlled at the factory.
Now getting back to YOU.
You have a problem that you can not seem to identify or fix so you have decided to try to overcome it by fitting a new carburettor.
Nothing wrong with that approach.
However that will only work , if the new parts you are fitting are actually good & fit for purpose.
You have no way of assertaining if the carb is good or bad so in those situations it is prudent to get the carb from some one who stands behind what they are selling .
Amazon & ebay retailers do not do this in most cases they are nothing more than a person who imports parts, send them to an Amazon / ebay warehouse who store & dispatch them to you.
