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! |

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 |
