Re: How Important is OMC Ignition Timing?

[frankr]

Reading through all this, may I add one thing? The purpose of using the timing fixture is it is more accurate, that is the points will open at exactly the right moment. It also takes the human error out of the feeler gauge method. Besides all that it just plain is easier. Having said all that, once you set the points with the timing fixture, if you then check them with a feeler gauge, they may or may not be exactly .020". If they are not, do not reset them per feeler gauge or you will be defeating the whole purpose of using the timing fixture. In other words, the timing fixture is correct over the feeler gauge.
