Quick fix
Bolted it in , mower started up and ran at proper rpm, no leaks or engine missing or skipping noticed! Alot quicker than rebuilding the one that came off it!

Easy fix - don't bother trying to clean out old one.
Easy fix - 20 minutes tops to install and motor ran perfectly after install. Previously tried cleaning out old carb which turned out to be a waste of time. For $16 shipped, this is a no brainer to bring an old piece of equipment back to life. Installed on an old Yard Machines edger from Lowes.

Started on First Pull!
My carb was leaking on my very old Tecumsah mower. Got this replacement carb (plus a new air filter) but was skeptical I'd ever get it to run w/o knowing how to tune it (mixture, idle speed, etc). Installation required removing protective cover to access inside bolt and fiddling with the accelerator connection proved a bit difficult but once it was all hooked up, I primed it and VOILA!, it started and ran perfectly. Obviously tuned to run from the factory. YRMV, but I'm a happy, satisfied camper!!

Floats full of gas don't float.
This part was delivered on March 7, 2026 and installed on my Edger shortly after that. I used the edger a few times until June 2, 2026 when I found gasoline running out of the air filter. When I removed the float bowl, I found the float assembly was half full of gasoline. This is a manufacturing defect.

Works like a charm
Got the carburetor a few weeks ago and finally installed it onto my ancient mower. Also bought a new Sparkplug & airfilter pack just to be sure all is ok. Installed, primed a few times Pulled the cord and all was go, go, go. Just needed a slight adjustment of the mixture to make it run smooth. :-)

Quick install and an even faster mower start up!
I installed this on an old 15+ YO lawn mower. Started right up (after I remembered to connect the spark plug). Great product, and value.

Works awesome
My old lawnmower would no longer start, at times it was taking 30 minutes to get it going but finally stopped working last week. I thought about how to fix it and decided to change the carburetor. First time working on a small engine, took about 35 minutes for me to change with zero experience. New carburetor works awesome. Lawn mower started on first pull. Just have to figure out how to adjust the idle speed now. Thanks for an excellent part for my 15 year old lawnmower.
