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. |

thats weird
I'll let the experts jump in but the dwell is measuring the point gap that shouldn't change with rpm (maybe a wobbly shaft?) the gap shouldn't change with timing... it should always be the same gap. I'd pop the cap and check the gap with a feeler guage while at the peak of the lobe... may need to roll the car forward or back to find peak. hmmm.... |
