Compatible with 2022 Ariens Deluxe 28
Super easy to install. Probably took me about 45 minutes and only because it was my first time replacing this carburetor, otherwise this is a 20 minute job. My snowblower now runs better than it has in a long time. Now I just need to remember to turn off the gas when shutting off the snowblower so I stop leaving gas in the carb. The only ding I'd give this carb is that it doesn't come with the gaskets. I'm not docking a star for this, but c'mon, it's like a 10 cent part. Just add it to the box.

Just what I needed
Works very well. My snowblower never ran right from day 1 (backfired, surged,would not idle}. Installed this carburetor,runs fine now. I strongly recommend.

Easy quick fix! Ready for another winter! Bring on the snow!
Arien’s deluxe 28 wasn’t working when I tested to get ready for the winter the other day. Emptied gas/added new, tested spark plug nothing was working. I decided to Order this carburetor, replaced the next day in about 20 minutes, fired right up with the electric start and manual pull. No need to spend extra on OEM , this one works great!

Running Lean No More
Had an Ariens Deluxe 28 snowblower that was running lean (had to run with partial choke all the time) which was limiting my power output - machine is only 4 years old. Tried pulling and cleaning the existing carburetor with no improvement. Purchased this replacement and it’s working perfectly now. As another reviewer stated, it’s not worth trying to clean/rebuild your exiting carburetor if your machine is running lean - just swap it out with this replacement and be done with it.

May want to look at Huayi 520-0353 with gaskets
If I had to do it over I would order the Huayi 520-353 as they are an OEM supplier and their unit comes with a new set of mounting gaskets. I do not understand a company like Stens not supplying the necessary gaskets.

Snowblower Carburetor
Purchased a carb for my Ariens snowblower because it just wasn’t running right. OMG so happy I bought your product because I installed it and the engine then started up first pull and runs like a beast! Best investment ever, would’ve cost more to just have the old one adjusted. VERY SATISFIED CUSTOMER from Buffalo, NY!!!

Avoid! Does not work on Ariens 921046
Waited a crazy amount of time for this to arrive. Be aware that there are absolutely no gaskets included with this kit (unlike any other similar kit on Amazon at half the cost). Once I disassembled the crazy amount of shroud material on my Deluxe 28 Ariens blower, made the simple swap of the carb. The replacement Stens carb fired up pretty quickly, and just about send my machine into orbit with regard to RPM ... dialed back the RPM via throttle ... at high idle it drops down to just about nothing ... bogs down when attempting to move the slightest bit of snow, then flies back to wild high RPM (literally flames coming out the exhaust) . I am too afraid to run it, as it will most certainly cause engine damage, going to try my luck on the higher rated $24 carb instead. Total waste of time on this one. Double checked all model numbers and part numbers against my LCT engine code, the 20001171 is definitely the Ariens part number for this carburetor, and the part number provided by Stens. It just doesn't work.

Great OEM replacement
Worked perfectly on my 921046 Ariens Deluxe 28. Only wish it came with the gasket so I didn’t have to be so careful with the old one.
