**HELP** Fast/Jumpy Speedometer

[ashx2]

Need some info from the powers that be.......

I put in a new cable in the '72 yesterday, and it seem to fit, but I'm beginning to wonder though. I took a ride after putting it in and the speedo seemed to be not only a little jumpy, but also fast.

As I turned the corner it said I was doing 10-15mph. I made the turn from a dead stop, so I know 5mph would have been more reasonable. Even going at what I would estimate @ 30-35mph it was reading anywhere from 45-50mph.

I'm kind of wondering if the cable might need to be a little longer maybe.

Has anybody else suffered from this kind of aggravation?

Thanks,
Greg
