Here are the typical things that I find on commercially rebuilt Q-Jets (including those from "reputable" builders like Holley):
  • Mixed-matched parts from multiple years Q-Jets (like airhorn from a Pontiac matched to a float bowl from a Chevy)
  • Power piston stop pin cut off
  • Idle air bleed holes plugged with lead plugs
  • Incorrect jets and rods for application (often "generic" no-size parts)
  • Incorrect float type (brass float)
  • Incorrect float level
  • Missing parts
  • Internal passages plugged with sand from sandblasting process
  • Internal metering orifaces drilled out or removed
  • Secondary throttle linkage misadjusted
  • Throttle plate broken from improper installation of shaft bushings
  • Warped/damaged parts used resulting in no passage continuity for fuel passages through airhorn.
  • Incorrect gaskets used resulting in blocked fuel and/or air passages
And these are just a few of the things I guarantee you will find in a commercially rebuilt carb. You have to identify and fix each one of these problems before the carb will ever run right. I have had several of these carbs that were in such bad shape that rebuild was not possible.
