Quick. Look at this carb whose auction ends in less than an hour. Will it fit an Olds 307 on my 1990 Brougham? It looks like a good buy for a rebuilt one.

Forget it, that is an early non-ecm Q-jet. It's difficult to tell if it's even an Olds front fuel inlet carb.
Looks like it's been sitting around for a long time as well.
If your carb needs a rebuild contact one of the rebuilders linked in the other carb posts.
You need to look for a E4MC carb, 90% if not 100% all had Olds fuel inlet. Olds 307's aren't happy with electric choke. So avoid E4ME's. I know, everyone likes them, I have done experience with both on my carb, and the hot air choke is best.

electrics are great on paper but a friken joke in the field.

I actual have a Q-Jet sitting in the garage. I tried to put it up on Ebay, but it didn't sell. Still looking for one?
You can find an electronic carb on other 307 equipped cars as well, if you have a local wrecking yard available. Of course, you can count on rebuilding them, but at least it's a source of finding a factory carb instead of a mass-rebuilder special.
Electronic carbs are no worse than monkeying around with any electronic components/sensors on a vehicle. I rebuilt the original one on my FWB, set it to factory specs per the service manual, and it works fine. Of course my preference would be a non-electronic version, but I can live with this one.
I don't feel there is any tricks to the E4M series vs the 4M or M4 series. Just some unique adjustments that you don't have on the 4M/M4....

This thread needs to be put to rest. That car's done gone and sold! :duh:
