There is a threaded hole on the right side of the '62 235 head that I do not know what it is for. It is at the top of the side of the head and right in the middle from front to back. The coil mounts aft of the hole. What is this thing for? It is threaded and it has a threaded insert in it with threads on the inside of the insert (like it is supposed to size the hole smaller). The problem is that is looks like it leaks oil a little. Any ideas?


How did all this sawdust get under the hood?
