It's the Chinese built 19 hp model. Jack's Small Engines sells a head for $161.00What hp is the engine? What is the model number? There are several lawn & garden salvage yards that might have a head for sale. Have you checked on the Kohler site for parts?
I did that with an 8 hp B&S one time and it was a short lived fix. I personally would not go that route.You can sometimes place the seal back in and peen around the edges to hold it in
Local machine shop is repairing it for around $60. Thanks for all who replied.Hi a good engine machine shop can repair that seat, pretty common these days with allthe alum head engines
