Kawasaki FD 731V Vs Fd750V carburetors difference

I am looking for a Carburetor replacement for a FD731V AS09 engine. I can not locate an exact replacement online.. It may be because it is an older unit I see some Fd750V.
Are the carbs the same or will it make a difference. They look the same, I don't know if they may be jetted different or something.
Are these part numbers inter changeable or equal replacements 15003-2879, 15003-2974, 15003-2063?
The number that I found on Kawasaki blow up view of the carb assembly shows E)180-A893A but I can not find any other reference of that number?

Thank you for the help.

You are looking for 15004-2063 carburetor. The one for the FD750V will be jetted differently. The 15003-2879 isn't listed as former PN for the 15004-2063.

To be perfectly honest, I do not know what carburetor I am looking for. IT's for a FD731V AS09 engine and I am trying to find to correct carb.
Will the 750 carb that is jetted differently be a problem for the 731 engine. Probably has more fuel but will the governor control the engine speed ok?

That's why I actually bother to look up your engine on Kawasaki Engine website and posted the correct part number you need to order. Some here just throws out info just to be doing so which a major peeve of mine. And I hate working equipment that been hacked repaired as I have to undo all the hacks before actually getting to the real problems.

As will the 750 carb be a problem? Yes it will as the fuel/air mix will be over rich. Or another way of saying it would like you running the engine with choke partially closed. Too much fuel in the fuel/air mix is just as bad as too little fuel in the fuel/air mix. And top that even the linkages can be different.

In your particular carburetor there are four metering jets and each one is a different size as determined by Kawasaki engineers to provide the correct fuel/air mix for your engine at different speeds and different loads. Actually they got these jets down to the thousandth of a millimeter.

Wow . That k you very very much .
I tried to lookup on Kawasaki website but I didn't find that information. You must have to be a dealer or have a dealer login to get it.
Thank again.
So where is a place for me to by a carb at a good price, is that possible?

That probably because that engine is probably on a John Deere and Kawasaki USA doesn't do IPL for them. I just used an outside US Kawasaki site which have saved me and my customers a considerable amount of money as the parts are available in the USA when you know the Kawasaki PNs.

Now as for a purchase there is not really any god place as all are fairly high in price. They do list around $406 and I do get about $75 off by going the distributor but you must be licensed as a retail business. Now there is on one listed on eBay for less than my distributor price that claims to be OEM. And there is one aftermarket for $101 on eBy too but I would careful there as a lot AM carbs are not up to par. Just search using the PN I gave and what you find one for.

Thanks, let me ask and stupid question.

Can I buy any of these carb numbers above? Should I only buy the latest version. Any way to find out what the reviosions were to the carb's?

All I know for sure is when I order one of the older numbers from my distributor it is automatically superseded to the latest number. Most time the supersedes are just they are using a new vendor to source the carburetors. Otherwords instead buying from Company A they now buying from Company C. And there are times a company with multiple lines just a suffix or prefix to part number they acquire the line just to indicate a different line just there are duplicate part numbers. Sorta like the Ferris the other day where just add "FS" to end of the part number, same part just a new part number and sometime a new price. Or something like JD does to hide the OEM part numbers so you have to by from them (they think but sometimes I can get past that BS).

This my database comes in handy for my own use as I enter crosses as I find them.

Just order the latest supersede and don't worry about the versions as a lot of the time they are just changing vendors.

I replaced the carburetor and at least it will start. It doesn't get full rpm, only around 3150 to 3300. It seems to me it used to be around 3700 rpm.
It barely has enough to start the PTO. It will run the it a few seconds with the PTO engaged and the choke on full or 7/8 . It dies but will restart.
Any new suggestions? It seems it not getting enough gas, right? Or is it a another bad carburetor?

Do you have a digital tachometer that is determining your engine speed. 3600 RPM is maximum for a small engine, however, many of the newer engines are set up to run 3150-3300 RPM. If you have to run engine on full choke or close to full choke, then the carburetor you ordered is wrong. You are manipulating the air/fuel mixture by running it on choke.

Ordered new carb, it starts but still dies after about 5 or 10 mins but does restart. It runs for a short period. It will run a long time with no load or PTO but under load it only runs a short time.
How do I correctly adjust the carburetor. I have already removed the he black caps so it can be adjusted but can not find exactly what these screens do or what they do each! Which is high speed or idle?

Ordered replacement carb but it doesn't reach enough RPM on about 2700 needs 3400 at least. How do I adjust the carb and what are each of the adjustments with the black caps for. I have already removed and adjusted them out about two and a half turns runs better but not good enough (I adjusted them based on information that the place that I bought the Card from recommended).
Still need adjustment information for the carb please!!
