perfect fit
installed on my mower in half an hour. Primed the car, and it started right up the second pull and runs perfectly. Well worth the price, much cheaper than paying a repair shop.

Good value, good fit, decent replacement part
Perfect replacement for a newer Briggs powered push mower. Fit perfectly, works perfectly. Came with new throttle springs which was a nice bonus. For the money, this was a great replacement. Mower runs like new!

Good value at a great price.
This carburetor is a great value and worked out well for the price. However, it's important to note that it’s not a complete unit—you’ll need to transfer a few parts from your old carburetor, including the throttle and choke plates along with their linkage. This step requires a bit of mechanical skill and might be challenging for someone who isn’t very experienced. That said, once everything was installed, my lawn mower started on the first pull and ran beautifully

Don't buy it.
B&S plastic carburetor is a joke. When I first bought the mower it ran fine. The second season, it would not start. Cleaned carburetor jet; then it ran. I purchased a new one through Amazon; it wouldn't work, so I built one from parts of the new one and the old one. Next season it would not start. After reading the glowing praise, I bought and installed this new one. It would not start at all. Then I rebuilt one of the older ones and the rebuilt one works. I have not done anything with this one, just keeping it for parts. Instead of buying this one, simply clean the jet in the old one. You can find everything you need to know on YouTube.
