1976 Cadillac Quadrajet idle problem
jbmoffo:
I thought you'd say the acc. pump.
Never rebuilt one...so...how difficult are we talking?
429bbf:
first step . buy cliffs book off this website. then order an sr. kit total for the 2 appox.100.00 it doesn't have a lot of miles but be sure to check for throttle shaft wear. most will need bushings. cliff also sells a kit for that. if you just want to get by you could buy the acc.pump and float but buy the time you buy a gasket and such your just going backwards. i usually spend around a 100 for parts that would also get you a new electric choke coil.you can spend upwards of 200 if you need pull offs and idle tube or you can buy a
[remanufactured carb
. and have to do the work twice.get the book do some reading and make a decision.fwiw
Cliff Ruggles:
The choke flap should be fully open in about 2-3 minutes. Most likely the E-choke is defective and it's just opening due to engine heat not from the choke. This will cause all of the issues that you are seeing.....Cliff
73ss:
First things first..... Is there 12V present @ the choke. Most of these were wired through a oil pressure switch so 12V would be present only with the engine running.
I didn't think they had elec choke in '76... Was it converted over?
jbmoffo:
Not coverted. 12 volts present. And Oil switch is brand new. Did this before the switch was replaced, too.
After I turned it clockwise toward the notches, it lines up with the LAST notch for RICH and seems to be running much better. I don't get much of a chance to drive it, so the next time I am out with it, I am going to see how she responds. The accelerator pump really needs replacing though.
