This is an authentic part that has been sourced from the original manufacturer for use with Honda engines that are commonly installed on a variety of lawn and garden equipment. The carburetor connects to the cylinder and is used to supply the engine with a mixture of fuel and air. Unfortunately, over time it may wear out or get damaged eventually requiring a replacement. To ensure the proper repair procedure, refer to the appropriate diagrams for your model. A wrench set will be needed to replace this carburetor assembly. Keep in mind this high-quality assembly is sold as an individual item.

Super easy, works great.
My Honda rototiller hasn't been easy to start and ran very rough, it's over 10 years old. I installed the new carb assembly and spark plug then primed the system and it fired up first pull and runs like new. No carb adjustment necessary, it starts, runs and idles as a new machine.
Thanks.
