| vac. advance |
| By frank - 02/18/2001 10:45:56 PM; IP 209.134.88.23 |
| I have a 69 428 cj and the vaccum advance went out. So I went to autozone and bought one. The one they had was adjustable and I put it on with out adjusting. After I started it it ran fine so I drove it, and the question is at Idle the tach is fine but if I rev the engine up and hold it there the tach will jump up and down about 600 rpms. I was wondering if it could be the advance and if so should I adjust it in or out. I don't think it's the tach because it worked fine before the new advance. Any help would be appreciated. |
