L78 Holley Rebuild...

Voila...one primary bowl now equipped for a vent assembly.

Next thing was to correct the warp that was present on the metering block surfaces. If this step is skipped (and it often is), the carb can develop internal leaks that can cause all sorts of grief and aggrivation.

The secondary side received the same treatment.

The baseplate surface receives the same treatment as well

The baseplate itself is also machined flat again on both sides instead of just the manifold side as many rebuilders do:

The bottom:



Finally, the baseplate was bushed for the primary throttle shaft, as despite the fact that this is a low-mileage carb, the funky secondary mechanical conversion that was noted earlier must've caused some extra wear as it definitely needed to be bushed.

Finally, the carb was buttoned back up and all of the adjustments were baselined for re-installation.



Ain't much to look at when compared to the restored pics we're all so used to seeing, but this is what a 38-year-old carb looks like in its "natural state."

The other side:

And lastly, the business side of the carb:



And that wraps it up. The carb definitely had some issues from its previous rebuild, but it should be good to go for another 38 years now...as long as Tom gets that dirty fuel issue resolved, that is.

Hope y'all enjoyed.

Just curious Eric... did Tom choose not to have the carb re-plated? I would have thought after all the machineing and new parts,it will run like brand new and it should look like brand new.

Extreamly interesting thread by the way!
