'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.
