Here is a nice original head for an Associated Chore Boy or United equivalent engine. Please check the measurements to make sure it is what you need. The valve heads and seats look great. The valves also feel good in their guides. Very hard part to find. Its for a 3hp to 3-1/2hp size engine. CHW (I think, its hard to read). The mounting hole pattern is 4-1/4″ x 4-1/4″ measured from closest hole to next closest hole on center. The carb mounts with 2 holes about 2-3/4 apart on center. About 7-1/2 in overall diameter. The raised area in the center is a little under 4-1/2 in diameter. Has been repaired but looks good, see pics. Most items will go out faster though. I have many good parts and pieces I will be listing in the next few months. I try to do a very good job of listing everything I sell in a very accurate manner to explain all the good and bad points with the pictures and in the description. So if someone doesn’t pay I will ban them from my listings and also tell all my friends who also sell engine parts on here who to watch out for. If you haven’t caught on this is supposed to be mildly funny but yet serious at the same time. If you decide you don’t want it or find another one cheaper you I won’t take it back. For example if my measurements are wrong I would take it back. So here it is. Rozevink Engines LLC 14316 St Rt 281 Holgate, Ohio 43527. Check out my other items.
