Do any of you guys have a little 'stumble' at idle? I just cant quite seem to get a nice smooth idle and I'm a picky bastid! I just want to see if this is happening to more people with the 60's, or if maybe there's something else going on here. I road race all summer so I want to be sure it's just an annoying idle-tuning issue, and not something more severe like a bad valve spring or something like that... I assume it's not, since I can change the way the shudder occurs, and it stops with the A/C on, or anytime other than holding revs at a standstill.

Any info would be appreciated. I know a few of you guys are as hardcore into tuning this things as I am myself, so lemme know if anyone has any suggestions.

 

I don't think you are alone. Some of the Pittsburgh guys seem to have the same problem, might want to check with them. I pulled this from another thread...
