Carb school

There are some good rebuilders if you search online. I have had Edelbrock, Carter new carbs and rebuilt Qjets. I currently have a rebuilt factory Qjet on my 454 and it runs well. I would just get a rebuild from a specialist in Qjets - I think most mechanics are not skilled enough to rebuild Qjets - it takes some experience, tools, good quality parts to do a good rebuild, not just a cheap rebuild kit.

Whatever you do, get a manual choke kit ($12) - that way you will know for sure that your choke valve is open all the way when you are driving and closed all the way when you first start it up. With an automatic choke you never know where the choke valve is, either hot air or electric.

It could be that your choke valve is not opened all the way when hot now - I would check that out first.
