This replacement part is a cylinder head.

If the engine is no longer starting or is struggling to start, it might be the cylinder head malfunctioning. If there are unusual noises coming from inside of the machine, this part might be out of place. This is a genuine replacement part made by Midwest Engine. It is an OEM replacement part which will ensure a proper fit. This part is sold individually.
