Trying to find correct replacement carburetor for my Honda mower

[kprojects]

I have an older Honda push mower - real old.. I believe it may be from the mid/late 90s? Maybe earlier? I received it from my parents about 15 years ago.

Anyway, i've cleaned out the carb a number of times over the years and it's currently not running. Since it's in bad shape, I wanted to order a new carb but can't seem to find the correct one.

From the engine code (SHN135U1G1RA) it 'should' be the GCV160 carb, but after ordering it I realized that the gcv160 carb's stud holes are even across, mine are offset.

For age of mower help, this has a plastic deck which I know they stopped doing at some point..

I've attached some pictures - any ideas?

Have you checked spark, compression, and valve clearance? If not, throwing a carb at it blindly may well be pointless. Not sure on that series, but other Honda engines have the engijemmodel and serial cast into the front . . . should be easy to cross reference from there, but then again, I don't see anything that tells me that a proper carb rebuild would not be enough.

Thanks for the reply - just got the numbers from the block to help determine the correct one - and uploaded the pics above.

Yes, i do have spark, have not checked compression - I don't have the tools for it. Last time I cleaned the carb however, I noticed that the float pin was missing (or my brother-in-law lost it since he wanted to clean it out while I was doing other things).. so I either need to find a float pin or find a new carb. They're pretty cheap on Amazon, the one I purchased already was $14.99.

Update: with the help of my local honda dealer I was able to figure out this is the 16100-ZG9-M12 carb. Hopefully this helps someone out in the future.

You won't get a Honda carb for that - just dubious quality Chinese ripoffs . . . . The original will almost always be better if you can keep it going . . . You might check with your local equipment shop - they may have a pin in the spare parts pile that you can have.

Other good news I see! You have the GXV and not the GCV - a far better engine! The GXV is basically the commercial line, whereas the GCV is homeowner grade . . . . This should run pretty much forever if cared for. I have a 1989 or so mower with this engine, and other than needing rings, all else was still in spec this spring, 30 years of significant use later!

Looks like you can buy just the float and pin from Honda as well:

For future reference, Honda does have a good parts lookup on their web site: https://peparts.honda.com/powerequipment#/browse/lm/hrm/hrm215
