Well I got a new head for my ranger and I knew how to time it. The old head was cracked but on the cam gear had a lil arrow showing where to line it up. But this new head cam gear doesn't have any sign of an arrow on it. Question is how do I know where it's in time or not with no arrow? The other head is at the machine shop. They kept it. I didnt realize this didnt have the arrow till today.
