Reply To: Timing Question

If you can set the points without using the tool, you can do it using the tool. The tool has nothing to do with the gap. It just indicates when the gap is correct.

Are you using the meter with all of the wires hooked up to the points? If so, you are going to have an ohm reading both with the points closed and open. When they are closed, the circuit is thru the points to ground and when they are open, your meter will sense the circuit thru the coil to ground. Can you turn the chirp off and watch the ohm reading on the meter instead? The meter has to be set to its lowest reading, usually 200 ohms or less. It should read zero or very close to zero ohms with the points closed but just as they start to open the reading will increase slightly as it is now reading the resistance of the primary winding in the coil. You want this change to happen as the pointer on the timing tool is in between the timing marks on the mag plate. This change of ohm readings happens as the points are just starting to open and you will not see any visible gap between the points as this happens. The ohmmeter reading lets you know when its happening.

For years the OMC/BRP points have been made in Turkey and I’ve never had any problems with them but I don’t know where they are made now. If the rubbing block on them is a bit short they will be a bit harder to set and they may need a nudge with a screwdriver to get them where they should be. Here’s a link to a previous thread where someone was having a similar problem with their points. Note the readings on my ohmmeter and the position of the timing tool in the photos.
