Found a bad choke pulloff, causing the choke to be too rich. Let's see if that fixes it.

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.

Electric Choke adjustment: rich and lean extremes
In this video, I am purposely changing the rich/lean adjustment wildly in order to show the effect. Your actual adjustments would not be this extensive, but if your engine is loading up and not running very well, the choke or an aspect of it's systems may be the culprit.

Everything you wanted to know about automatic chokes but were afraid to ask
I've noticed many people drive vehicles with inoperative chokes. Even though chokes can be intimidating, repairing and adjusting them actually is very simple. So, stop pumping that accelerator and follow along as we look at how chokes work and how to repair them.





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.

'77 Chevy K20: Quadrajet Choke Pull Off and Fast Idle Cam Observations
1977 Chevy K20. 350 crate engine. Rochester Quadrajet 4MV carburetor with divorced choke. Truck suffers from unexplained hesitation and bogging when in forward gears. Tends to rev just fine after a few minutes of mixed idling and high revving. Checking choke operations as well as a possible sticky fast idle cam as part of the process of elimination. - Truck is allowed to idle/warm up until 2:25 mark, at which point the engine is revved to about 2,000 rpm, and can be heard bogging (a hissing sound can be heard). The fast idle cam is seen dropping. Fuel flow can be seen in the glass-cased fuel filter right before the carb as remaining steady. - The engine is revved again about three more time up until 3:00 minute mark. The engine revs slightly higher, but the hissing and bogging can still be heard. - Engine is revved again at the 3:35 mark, slightly past the 3,000 rpm mark. Hesitation and hissing still evident, but less so than before. - Engine revved at the 4:25 mark to about 4,000 rpm. No hesitation or hissing heard. - Transmission is slowly shift through every gear starting at 4:55 mark. Shifted back into Park at 5:05 mark. - Engine revved again at 5:10 and 5:17 marks to 4,000 rpm. No hesitation or hissing is heard.
