Default Re: Zoom Slanthead Engine

It is very difficult to spot the pin hole in the casting because of
the location. What led me to find it was the intake casting of cylinder
is different than the other engines. Same location on both sides of
cylinder intake. Sorry I had to return the camera that I borrowed.
Stay above bolt holes and go all the way back to cylinder where fins attach.
At first I thought it was a black speck , so on jet black engine you will not
notice it.
