Accurate points timing

[mattjeanes]

My 1974 15hp Evinrude has got points based ignition and I understand the timing is set by getting the points gapped correctly. This leaves me with the following questions:<br />1. How accurate is this?<br />2. Does a wider gap give advanced or retarded timing? (If would much rather go retarded than advanced to play it safe)<br />3. Is there any way of checking the timing once set?

Re: Accurate points timing

Timing is set by the rotational position of the stator, though it is affected by the point gap also.<br /><br />Set points at .020" gap and leave them there.<br /><br />Your manual will guide you in setting the linkage and synchronization of the throttle position and magneto timing.<br /><br />Good luck.
