I just had my tach rebuilt and installed a new cable. I am getting a lot of needle bonce. Is there anything I can do to stop this.

Re: 66 Corvette Tach needle bonce
Under what conditions does it bounce? At idle, it should be fairly stable, if you are reving the engine, bounce is normal to some extent.Bill Clupper #618 -
Re: 66 Corvette Tach needle bonce
I have read that cable bounce is typical of a poorly lubed cable. Have you tried any speedometer cable lube?

Add on...
Plus, if the cable has run dry, there's a good chance the square drive end that enters the distributor has 'chewed' or 'rounded' corners now allowing it to slip as it spins. If this is so (visual verification required), it's time to pull the tach drive cable's inner cable, clean the sheath of dried/caked lubricant, purchase a cut-to fit, replacement inner cable, liberally lubricate it, and re-install it in the outer sheath to eliminate the drive cable's slipping action and consequent tach needle bounce....Comment

Re: 66 Corvette Tach needle bonce
Try loosening the cable hold in clamp, at the tach, a turn or so, this worked for me. Of course the cable needs to be lubed as well. Look for any sharp bends in your routing.... BillComment
