Dwell is 49 at idle, jumps to 50 just off idle and goes all the way to 53 at full advance (3500 rpms), advance and retard hoses were hooked up for dwell check, I know to unhook them for timing. Is that right, or do I need to unhook them for dwell, as well.
Possible dizzy advacing plate issue? Car has a miss at 3kish, I'm trying to squash. Stock 74 2.0 djet. timing is set at 29. |

The points are a spring. If you activate the spring in enough cycles per minute you can get spring bounce just like a valve spring (kinda like floating the valves) in which the dwell would change with RPM.
Try a new set of points for fun or just get an electronic module (I prefer Led trigger, but your experience may be different) that would not be subject to dwell changes. Ferg, you are WAY to anal. That's 3 cups of coffee thoughts. |
