1984 Oldsmobile Cutlass Supreme Brougham

so all the last "details" are more or less resolved... so the car will go hoodless in the driveway and do its 15 minutes @ 2300 rpm for the engine break-in.

bummers. today, the car does NOT idle properly after it ran supah-dupah-fine Sunday, two days ago.

- open the throttle, runs better but rough.
- put some starting fluid, throttle at idle position,it runs perfect
- play with the choke, does not do any difference
- disconnect the mixture solenoid, still runs like sh*t

so, my analysis so far:

- maybe the fuel pump died?
- maybe dirt in the carb, clogged, runs at 50%?
-maybe a fuel line died and lets air in?

The verdict is - the car is not driveable, so the carburator will go for a full overhaul - lucky to know someone in the area who is knoweldgeable in these old carburators... this is a 40-year old carb after all.

meanwhile, cleaned the underside of the hood (will "paint it black") and was vain with the license plate... 😉

The carburator re-builder said NO and was in a hurry to hang up when I mentioned my carburator is a E4ME Quadrajet... 🫠

He said he done it in the past, but... it feels the guy still has PTSD from it!

Yeah, specialized tools and knowledge to set up those carbs. Only a few of the Quadrajet builders do them.

Since this is a CCC carburator, it should not have anything special - no special port for the PEVR, etc. The tuning must be turbo-specific of course, but the magic is in the ECM and the special MAP sensor that can read vacuum and boost. I may be wrong and missing something, however - and you are right, I'd be worried to ship it and then never see the same carb again and then find out the "rebuilt" carb just cannot work fine with a turbo.

First time ever I will own a car having a clean hood underside.

Ordered a few carburator parts (TPS, M/C solenoid, various tools) and will tackle a round of adjustment myself. There's a guy who does really precise videos on how to rebuild CCC quadrajets -
