4 Cycle RC engines
Here is the question. Do any of the 4 cycle engine brands in use have valve seat inserts that can be replaced? I am working on a 4 cycle engine that has 4 cylinders. The valve head dia would need to be maximum of .437. The stem dia about .125 & length around 1 3/16 to 1 1/2 long. Sure would like to locate the valves anyway. The seats is only needs for repair & not many would be needed. Thanks in advance, john
