I was driving when it seemingly randomly quite on me. I know a good bit and have built SBCs before but this is still stumping me.
The rotor was broken when it quite so I started with that. Replaced the distributor, wires, and plugs.
Replaced the Cam, timing set, pushrods, lifters, rockers
Brand new quadrajet
Triple checked my distributor stab
I have messed with AFR screws, idle set
I checked my valve lash to see if I managed to over tighten the rockers
I checked spark
I tried using carb clean to find if there is a vac leak
Someone please tell me I missed something obvious that I can fix.
Edit: forgot to mention also brand new fuel pump and complete distributor
UPDATE: After holding the choke open manually and hitting it with a spritz of starting fluid it started to idle and help it. Wasn't pretty and smooth but it stayed going for a good 1-2min until I let go of the choke.
The negative on the battery feels loose so I am going to replace that.
And the idle seemed to get better when I started pumping the brakes so I wonder if the booster is one foot in the grave causing a huge vacuum leak.
It's night now but tomorrow if I can I will adjust the choke and fix the battery ground at least and see if that makes a difference at all.
