I searched the topics on handheld tach's but I'm still unclear on this issue. I'm starting my rebuilt motor this weekend and the only tach I have available is a MAC EM710.<br />MAC claims it will work on engines 1-12 cylinders, it has an inductive pickup. Will this work OK? I assume it will as the inductive pickup will register each time cylinder 1 fires.<br />Am I missing something obvious here?<br /><br />Thanks!
