Compatibility & Fitment
This carburetor is a direct replacement for Honda's latest overhead valve (OHV) residential engine platforms. Key compatible models include:
- Honda HRN Series Mowers: HRN216 (all versions including VKA, VLA, VYA).
- Honda HRX Series Mowers: HRX217K6 and newer versions utilizing the GCV200 engine.
- Honda GCV Engines: GCV170, GCV170LA, GCV200, GCV200LA.
- Specific Engine Types: G5B, G5BR, S3B, and Type 7 configurations.
When to Replace
- Hard Starting or No Start: The mower won't fire even with fresh gas, indicating the internal jets or the auto-choke passage is severely restricted.
- Engine "Hunting" or Surging: The engine RPM fluctuates up and down at a steady pace, usually caused by a lean fuel condition or an internal air leak within the carburetor.
- Fuel Leaking from Intake: Gas is dripping from the air filter housing, which indicates a stuck float or a failed needle valve—a serious fire hazard.
- Mower Dies Under Load: The engine starts and idles but stalls as soon as you engage the blade or enter thick grass, signifying a clogged high-speed circuit.
- Visible Varnish/Corrosion: If the carburetor bowl contains white powdery residue or "jelly-like" old fuel, a full replacement is more reliable than cleaning.
Installation Tips
- Note the Gasket Stack: Pay close attention to the order of the insulator, gaskets, and air cleaner case. If the gaskets are installed in the wrong order or backward, the engine will suffer from vacuum leaks.
- Clean the Fuel Tank: Before installing the new 16100-Z9L-811, drain the old fuel and wipe out any debris in the tank. Installing a new carb with old, dirty gas will ruin it instantly.
- Check the Thermowax: While the carburetor is off, inspect the auto-choke thermowax plunger. Ensure it moves freely so it can properly actuate the choke on your new carburetor.
- Avoid Over-Tightening: Tighten the mounting bolts evenly by hand. Over-torquing can warp the plastic air cleaner housing or the carburetor flange, leading to air leaks.
- Filter Saturation: When installing the new air filter, ensure the seal is seated flat in the housing. A poorly seated filter allows dust to bypass the carburetor and score the engine cylinder.

Value for Money- Exceptional performance and features!!!!
This vacuum/mop system is wonderful! I highly recommend it. This is bi-far the best vacuum and moping system which effectively cleans my floors and carpet. I've always been on the lookout for anything that can lighten my cleaning load.
it’s been a real game-changer for my household routine. The self-washing and self-charging features are a huge win. I no longer have to worry about cleaning the mop or making sure it’s charged; it takes care of itself.
It moves around furniture and other obstacles smoothly, rarely bumping into anything. It easily navigates tight spaces and corners, making sure every area gets cleaned.
Value for Money: Considering all its features and how well it cleans, I think it’s a fantastic investment. It’s made keeping my home clean so much easier and less time-consuming.
The robot vacuum was able to map my house successfully, the battery life is a bit longer than my previous robot vacuums, the suction is also great. I saw it go over crumbs in the kitchen and it picked up without any problems, and also has a mop functionality. It has a functioning app, very easy to use. The vacuum is also very quiet. By far, this is my favorite robot vacuum and I’ve tried many as I do not like to go around the house mopping and vacuuming. 10/10 would recommend this model - worth the investment.
Overall I could not be happier with this purchase, my home is the cleanest it has been since I’ve first moved in.

A blessing for “unforgiving” flooring
We bought an 1800s home that was 90% hardwood, but the previous owner made the decision to tear out the hardwood in the kitchen. Unfortunately for us, the flooring we picked to replace it was what I call a very unforgiving. I didn’t realize it until it was too late, but it shows every speck of dust and every muddy paw print. With two dogs, my floors looked like they had not been cleaned in years, but it was being mopped on a daily basis.
Enter the Narwal. I’ve included a photo of what the floor looks like today post-clean on a typical winter day in the north (dogs and people running in and out, tracking and mud and snow everywhere). Look at it! It has a shine! In an hour, it will be dull again from the dogs’ next foray into the snowy yard, but right now…glorious! But the best thing is, I no longer care about the dogs tracking up the floor. I can just run the Narwal again. No real extra labor on my part (other than occasionally needing to fill the water container).
I want to add a couple of points that I find interesting or that I think people might want to know to make their decision.
Both the roller and the side sweeper brushes are meant to prevent hair from getting wound around them. So far I have found this to be true. You can see the videos the manufacturer has provided that show how this works, so I won’t bother to explain it, just point out that I’ve found it does work. I haven’t had to cut any hair out of the roller since I’ve gotten it, and that was previously a weekly thing.
It does not self empty after vacuuming. However, it compresses the hair and dirt to take up less space. So while I was emptying my big self-emptying canister (on my Shark) about once a month before, I’ve only actually emptied this smaller dust bin once every one to two weeks. Initially, I was worried that this meant it wasn’t picking up as much debris and hair, but upon review, I discovered the compression factor they describe. You also have the option of using dust collection bags that you can take out and dispose of. To be more environmentally friendly, I have not chosen that option, but for people that may have issues with dust, I’m glad it is an option.
It self-cleans and dries the mop pads quite well. I did pick up replacements so that I could wash them, but I’ve needed to wash them with far less frequency than I expected. When I do pull them off to wash, I don’t notice any odor like I was expecting.
The mop water is used to both clean the floor and wash the mop pads. I think the majority of the water usage is to clean the pads, however. So you will need to refill that every 2 to 3 mops probably depending on how big your house is. You can use it with or without Narwal cleaner - do not use other cleaners, or you risk the device dying or messing up your floors due to over foaming.
My one tip is to use any leftover mop cleaner you may have from your regular mopping, and add a capful into the dirty water bin after you empty and rinse it each time. Because if you do not empty that out every day, the stagnant water WILL be stinky. A little scented floor cleaner has seemed to improve that dramatically for me.
Is it expensive? Yes. Is it worth it? RESOUNDINGLY yes. I no longer have to kill myself to have clean floors. And that is the best gift to give myself.

Amazing robot helper
Color: White
I’ve been using this robot vacuum for about a month now, and I have no regrets about buying it! It’s noticeably quieter than my previous robot vacuum, and the mopping performance is excellent. I really like that it has two large water tanks—one for clean water and one for dirty—which makes a big difference as it easily covers my entire house on a single run.
I don’t have carpet, so I can’t speak to how it performs there, but for vacuuming and mopping tile and hard floors, it absolutely deserves high praise. The battery is another big plus—it can clean my whole house before needing to return to the base to recharge.
The app is fantastic. The mapping is very accurate, and there are plenty of cleaning options to customize different areas of the house. The initial app setup did require some help, but customer support was quick and very helpful. Overall, I’m a very satisfied customer and would definitely recommend it!

Great upgrade from my old robot
Size: Freo S, Size: Freo S
I had a different robot vacuum for a little over four years, and it finally started giving out, so I decided to try this one. It’s definitely an upgrade. The first thing I noticed is that it runs much quieter than my old one, which I really appreciate.
The self-emptying feature is super convenient as I don’t have to dump the container every single day like I used to. It mapped my home surprisingly fast. It moved through each room for a minute or two and somehow had the whole layout figured out almost immediately. I did adjust the room boundaries a bit, but nothing complicated.
Cleaning performance has been solid. I usually run it on the highest suction because I have a cat and a couple of carpeted rooms, and it handles the hair pretty well. For hardwood, there are lower modes too. It also has a mopping feature, but I don’t use it—I prefer my regular steam mop for that.
Setup was easy, and connecting it to the app took just a moment. And it charges quickly too.

Great value, Easy Set-up
Size: Freo S, Size: Freo S
I just got this vacuum and honestly, I’m pretty happy with it for the price. Here’s how it’s been going so far.
Price: This thing is a steal. Works just as well as some of the more expensive ones I’ve had.
Set up: It took maybe 5 minutes to get it going, and I didn’t even need to look at the manual. Super easy to set up and start mapping.
Carpet: Does a great job picking up dog hair and dust on my low-pile carpet. Doesn’t miss a spot.
Thresholds: It goes over low doorways and small lips—no getting stuck.
Navigation: It uses structured light for obstacle avoidance, which is typically found in much higher-end models, and it really exceeded my expectations. The cleaning path is smooth, and it avoids furniture without bumping into anything. It just works.
Base station: Very hands-off. It docks and charges itself. Plus, I love how sleek and simple it looks.
