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.

New quadrajet set up
New air-gap manifold and custom/rebuilt q-jet. Sounds good but I still need to set the timing on the distributor and the carb is tuned already. Hope you like, nothing to fancy just a few revs and walk around...the Exhaust is true dual no x/h pipe and it has cherry bomb glasspacks(3 inch)





86 Monte Carlo SS - cleaning out the Quadrajet carb and flowmaster exhaust sound
This engine was pulled from the car in 1997 and left sitting in a crate until 2011. They left the fuel in the carb so as it evaporated it left deposits. Exhaust sound at 9:01 3 chamber Flowmasters, long tube headers. 2.25" pipes and I don't think there is a crossover tube.

How to de-bog your Quadrajet part 1
Sorry guys, I got the videos a bit out of order. The Rochester Quadrajet has gotten a bad rap over the years, often called a Quadrabog or Quadrajunk. In fact, this is a great multipurpose carbureter once you understand how they work and what not to do to them. In this clip I introduce you to the Quadrajet and begin explaining the theory of operation of these units. Enjoy!

Issues with my thermoquad rebuild. Instruction sheet doesn't quite match the carb, which it never does....





Rochester Quadrajet, the results!
Two mishaps, the first shown here, the choke coil I got was wound backwards, it made the choke butterfly wind up TIGHTER as the engine warmed up. I swapped on the one from the old carburetor fast enough, the second mishap made me feel like a crud and what did I mess up later that evening. The car would not start leaving the Etobicoke -Queensway show. It was not getting gas. We got it running by priming the carburetor, and boy, was I ticked at myself. In the end it was not my fault it looks like. The new accelerator pump umbrella and rod was a very poor and frail design, the umbrella came detached and stayed at the bottom of the of the pump well, and was a distressed mess. The maker will get a note from me. The upshot? The old assembly went in, all is perfectly fine, the slight tip-in hesitation is gone now too. Stupid lack of pride it seems these days making parts for even simple things like an old carburetor.
