My tachometer needle tends to jump around a lot, rather than swinging in a nice smooth arc. Any suggested fix? If others have experience here, I'd love to hear how you've fixed it.
Thanks! |

Thanks! Car still has points. Now I have some areas to start the troubleshooting process.

QUOTE(mittelmotor @ Jun 13 2012, 03:25 PM)  Thanks! Car still has points. Now I have some areas to start the troubleshooting process. on cars I have run points on.... I always notice an improvement when I reset dwell, clean up the points, and check the timing... I noticed on cars with points that the tach would be bouncy and it would get slowly worse without me noticing. worth checking your dwell and maybe replacing any worn points. cheap enough to try brant |
