  • Cheap and an exact replacement. Would recommend.
It was cheap enough and an exact replacement/replica of the OEM carb. Installed without issue and ran with no problem. There were no leaks. The one I replaced, the needle was worn and flooding the mower. Worked for my application. Would recommend.

  • 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!

  • Cheap, do NOT buy!!!
Bought in October 2025, mowed four times with it since then and it is pouring gas out. This is April 2026. Cannot be fixed. Took apart and cleaned yet still pouring gas. Do NOT buy!!! Cannot get a refund or replacement because it has been six months.

  • 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 ... show more
