Default Re: Holley 94 Rebuild - Secondary Carb

Took forever to get it turned down. Decided to use my drill using 220, 400 & 600 grit paper. Measured old shaft again and it came in at 0.277” and new shaft around 0.287”. Not sure what’s going on. For sure dirt/grime buildup in the base shaft bores was hindering the fit. Cleaned them out with a bit of PB Blaster. Also added a bit of machine (3 in 1) oil to help as shaft would get jammed up. Thought I might end up bending it like I did to an original one when working on the first rebuild. They are fragile.
