Does point gap affect timing?
Set Your Timing Last The dwell, as well as spark plug gap, do have an effect on ignition timing. The later the points open, the later the spark comes and retards the timing. The earlier the points open the sooner the spark comes and advances the timing. That is why timing is the last thing to be set in a tune-up.
How do I know if my points are working?
Test for continuity between the block and the stationary point attached to the distributor plate. Rotate the engine until the points are closed. Use the multi-meter to test for a good connection between the points. A slight gap when the points are supposed to be closed will keep your machine from running.

How does point gap affect timing?
A wider gap will advance the timing. The sooner they open the wider the gap will be. As you increase the gap, the dwell angle will decrease because the points will open earlier. The spark occurs when the points open, hence increased spark timing.
What happens if you don’t adjust the points gap on Lucas?
On Lucas points type distributors it is necessary to periodically adjust the points gap. If the gap isnt properly adjust, the engine may misfire, backfire, or not run at all. At the center of the distributor is the cam.

Can I set the point gap using one gauge?
Although it is possible to set the point gap using one gauge, it is much easier and often more accurate to use two. Let’s say you want to set the point gap at .019″. Unfold the .018″ and the .020″ gauges. When you can insert the .018″ gauge between the points without touching both of them, the gap is wide enough.
How do you check the gap between the points?
Turn the screwdriver and then check the gap with the feelerguage. The points gap should be between 0.014″ and 0.016″. You will know wthen the proper gap is achieved when the feeler guage slightly drags through the points, doesnt feel loose, and doesn’t move the points.
