It is a perfect fit for a 2020 BlackMax 25cc weed eater from Walmart. However as others have mentioned the gasket doesn't fit. The new gasket only has a hole where the dimple is on the new carb. Not a hole that allows exhaust gases to pass to the diaphragm for the fuel pump in the new carb.Luckily, I was able to save enough of the old gasket to use as a template. That allowed me to use a 7/64 drill bit to make the needed hole. Once the hole was made I used a knife to shave off the un-needed material. Then a butane lighter to clean the loose material still in the new hole. Only 1-2 seconds is all that is needed per side. As seen in the pic, the 1st hole was a little off. The second attempt was dead on.Once everything was back together. 5-6 pumps of the fuel bubble. Choke. The weed eater hit on 2nd pull. Half choke and weed eater was running. 15 seconds idle on 1/2 choke and 30 seconds WOT. Move choke to run/off and was running weed eater. Idle to half to wide open with no problem.Didn't change fuel lines or spark plug. Just changed fuel lines last year, but the spark plug is 4 years old. I did change the filter sponge.Will have to wait until next week to actually put repaired weed eater to work. But I'm 99.9% positive it will work. Will update after I use it a bit.FYI the issue I had with the original carb was the pump diaphragm was ripped. So it would not pump fuel even when pressing the bubble.Put the weed eater with new carb to work this weekend. Used 1.5 tank of fuel cutting weeds. Not issues what so ever. As of now I can recommend this carb 100%. Unless you can modify the included gasket (if needed), you will need to order a separate gasket.

The gasket it comes with doesn’t have the smallest hole in the proper spot so you’ll have to drill or punch out the hole yourself for the ryobi 2cycle. I did this by putting the old gasket over the new one and using a sharpie to mark where the hole needed to be I then used a small drill bit and a blade to clean it up. Also trimmed off all the excess material on the gasket because it will get in the way of install. Worked perfectly. The replacement air filter it comes with is way smaller and not at thick at the original. It has a stretch fit and works but doubt it will keep debris out as well as the original factory one which is much denser foam. Carburetor, Spark and plug fit perfectly as well as the hoses and fuel filter. Works better than it did from the factory. Barely pulled the cord and it started and ran super strong. Highly recommend for the ryobi 2 cycle expand it has trimmer

Fuel line narrow for proper fit with fuel tank.

Carb is exactly the same as the one that I took off. Bolted on and fired right off.

Got tired of removing my carb on trimmer and cleaning it out. Even after cleaning it out, still didnt run like new. Put this on my ryobi and she's got a new life. Not hard to replace.

The 2 mounting holes and intake are ok, but theirs a 1/8 hole that didn’t line up. So I flipped it over and drilled my own hole. But it worked out started right up and idles good. The fuel lines that come with it aren’t the correct diameter. On my Ryobi they’re a bit bigger. They need to be because that makes the seal when going through the tank, supply and return. Used existing lines.

Surprisingly this fit perfectly, and runs perfectly. The spark plug was the exact same thing. The air filter, which is a little foam rubber ring, was too small and flimsy so discarded it and retained the original air filter. All in all I'm happy with this.

The media could not be loaded.  Everything was fine, except for the gas line the gas line, which is your most important part of the change I would employ people do not replace your gas line. Keep your current gas line do not attempt to use the gas lines sent by this product because he will get gas everywhere does not create a seal. It’s too small too small.
