What does it take to install new throttle shaft bushings on my Holley 4V 4160? My Holley manual said to have this done professionally. Is this an expensive procedure? I only paid $30 for the carb but it has been working great until the shaft started leaking.

Thanks.

You can buy new throttle plate assbly's from Holley post the list # and I will see if they list a replacement for you

Thanks for the info. My carb is the universal list# 1850 model.

Are you sure this is you problem. If your float level is to high it will leak out the shaft.

Yes - the float levels if anything are a tad low since they are level but don't flow over the sight plug holes.

Thanks for the suggestion, though.
