Need some help with my carb! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Hey guys, i'm having a problem with the quadrajet on my 86, more specifically the choke. Basically, the choke is on all the time, and will not open up. I can manually open it at idle, but once you give some more rpms, it closes again. Do any of you have any ideas? Thanks.

Check and see if the power wire has voltage going to it.

Yes check to see if ya got voltage then it it does try adjusting it by loosening the 3 screws and turning it counter-clockwise just tad.

you should check your choke pull off also.pull the hose off it and decompress the plunger and put your finger on the hole if it stays in its good and if it goes back out it junk and you need a new one.

When you are done fiddling with your choke, install a manual choke - choke problems solved forever - you control opening and closing the choke and by how much.

I might have to try that also. I tried turning it, but that didn't help.....I just put a zip tie around mine to hold it open
