Electronic Quadrajet - Choke Stat Lever and Fast Idle Adjustment 

By far the best video on the art of quadrajet adjustment on RU-vid! My daily driver is a 1978 Oldsmobile Delta 88 Royale with the 350, and I have been using Shell 91 V-Power since I got it as it had no ethanol. Sadly, every gas here in Canada was forced to have 5% ethanol this past summer. Even the 94 Chevron. So, the ethanol totally dried up my accelerator pump. Looked like a dried banana. Rebuilt the carb easily, but there is absolutely nothing on how to set the choke. Now I found your video, but it's late, so come morning the carb will get some TLC on the choke. I have owned many quadrajets over the years with no problems whatsoever, but this ethanol junk sure did a number on my old girl. Liked and subbed! Thanks a million!

Your content on Quadrajet carburetors is excellent. I just tecently purchased a '90 Cadillac Brougham with the 307 Oldmobile engine. I tecrntly rebuilt the carb and now have to make these adjustments. Its been about thirty years since i worked on these. This car brings back many memories for me. Just subscribed. Thanks for sharing.

Another excellent video!

Great video as always. At cold start, my '86 Caprice idles way too high AND take 5 minutes or so before it drops down to the second step of the fast idle cam. Are 1) fast idle speed and 2) fast idle duration both affected by the fast idle adjustment screw? Or could it also be because of choke stat misadjustment?

Question my car is an 85 electronic Qjet 4bb when I start the engine and kill the key after it runs it starts dieseling any advice ? Carb adj. cleaning?

Would the drill bit size be 31 or 5/8 in fractions?

Can you rebuild my carb
