I ordered this item to replace the carburetor on my Riobi trimmer. Jacks had the exact item. I ordered it and they promptly communicated to me that it was not in stock and that I would have to wait a week. It actually came in earlier, which they sent me an updated note keeping me in the loop. I received it and installed it. The trimmer started right up and ran as it did when it was new. Great communication from Jacks and good product. Thanks.
