Liek another reviewed said, none of the gaskets fit so keep the old one. My mower is a Yard Machines P510 11A 02MY700 which there is very little info online on this mower. The supplied air filter does not work with this mower and did not use spark plug or priming bulb, literally just the carb/bowl. Easy to install and the provided several inches of fuel line (which is just clear aquarium hose really but worked fine) was a welcome addition since I mangled the original fuel line getting it off. Job done!

Had to replace carburetor on YardMachines 20 " push mower. Worked perfect! Started right up. Went ahead and replaced primer bulb also that came with kit and fuel lines. Primer bulb was a tight fit but worked. Knew filter and sparkplug were wrong fit before ordering. I needed a new carburetor and threw other pcs away that was not needed. For the price, can't go wrong! After looking through other reviews and items, I chose this one. Would definitely buy again.

Worked good came with all parts nessasury

Perfect fit for the MTD 11A-B0S5700. Although I did have to use the old seal. None of the new ones were the core replacement. Everything else worked though.

The carburetor fixed the main problem on my mower, however the filter and spark plug do not fit my mower

Just what I needed to fix my mower. Not difficult to install, as long as you pay attention when removing the original carburetor, and put everything back like you found it. The hardest part was finding the right gasket, which really wasn't all that taxing. Everything you need is in the kit. Put it back together and you are back in business.

Wasn’t machined correctly. Would not prime. Hooked up old carb to make sure and it did. Threw this carb in trash.

I purchased two other carburetors on Amazon before I purchased this one. The other carburetors did not work.I work on small engines.The reason the other carburetors did not work is because the brass plug, shown in the picture, is missing.Without this brass plug a person cannot use the priming bulb to prime the carburetor.I started the engine with starter fluid but the two other carburetors did not run correctly.This is the carburetor to purchase. However, the filter may or may not fit your engine. But, the price of the carburetor is so low you can pitch the filter.

Perfect replacement for the Power More engine carburetor which is an MTD engine

Well it's a dud. You can't prime this carb because the primer passage is not open to be able to prime from inside the float bowl. I guess you get what you paid for. Amazon came through with the win to correct my return and of no cost to me.
