10PCS Metering Diaphragm Replaces, Metering Diaphragm Assembly Replacement for Zama A015053, Small Engine Carburetor

Rebuilt a carburetor on my granddaughter’s weed eater. Exactly what she needed.

This is also the correct diaphragm for a Stihl MS211C -- this model came with two possible Zama carburetors however the part number on this metering diaphragm is the same for both. My chainsaw had the C1Q-S120B carburetor. After installing the new diaphragm the chainsaw runs like new again. The old diaphragm had became distorted and very rigid. This is a very common problem. I have used mineral spirits or wd-40 to try and soften it and at least get it running while waiting on the new part....

I installed this in a 20yr old Stihl edger. This new one is significantly thinner than the original, so I wasn't sure it would work, but it does. I don't think the old diaphragm was the original (but is an OEM replacement), but from its inflexibility, I should have changed it a while ago. The diaphragm needs to be flexible to work properly. The new one certainly is flexible, floppy in fact, as it's so much thinner than the OEM. I can't predict how it will hold up over time, most likely it won't last as long as an OEM part. I considered deducting a "star" because of how thin it is, but given the price/quantity and the Pleasure of having it start easily again (for several cuttings), a deduction just seems silly. I'll see how it holds up over the winter.

A great price and quality on the shelf and a great way to make extra money and do good maintainance on your own equipment . Keep it on the shelf at all times. Agreat product.

works great, just as good as OEM

my weed trimmer starts up like new again. I could not find the part number for my cub cadet weed trimmer so this diaphragm look all most the same as the original part so i order and fits perfect and starts up fast like new again!

various small engines.

fit just right on my weed eater
