Holley Carb Rebuiding Part 3: Final Chapter
Finishing up the carburetor. I did not provide the step by step instruction that I wanted to with this series, but hopefully you will get some useful info from this.
how to minimize engine bog with a Quadrajet carb
this is to minimize engine bog when the pedal is to the metal. do not over tighten, very small spring...you want to try 1/4 turns or 1/2...q-jets are good if tuned properly. also when you are tightening screw it will have tension on it so keep the screwdriver firm. 1986 gmc sierra single straightpipe to cherrybomb. you will need a small flathead screwdriver and a 3/32 allen key. be sure not to tighten to much or else your vacuum secondary flaps wont open.

Identifying vacuum ports, late-style Quadrajet
I always see a lot of questions about what various vacuum ports do on a Quadrajet.
Here's a general guide that will point you in the right direction. Remember that there were many different Qjets over the years and vacuum port locations and number will vary. This video is representative of 1975-90 carbs.
Enjoy!
