Jet chip or edelbrock can if you want to send it to them but, it will cost you some coin! I do all mine. I have a shelf full of them probably 200 or so.... There is a book on how to rebuild and modify a Q-jet and it has all the in's and out's of one....

In order to make a Q-jet fully perform for you, you have to understand exactly how they were designed and operate because of there tempormental nature....

1st of all if you haven't already done it. Pull the rod off the air horn that goes to the choke pull-off....Get a allen wrench and a screw drive and set the air-horn via road testing.....
