I have disassembled a Holley teapot carburetor for rebuild and am facing the challenge of removing the brass discharge nozzles. In the past, I have ruined two of them by breaking the beaks off both of them in trying to push them out, I have noticed a notch machined into the tops of these nozzles and have been tempted to insert the blade of a flat screwdriver and gently try to break them loose. I have watched several rebuild tutorials including Hot Rod Reverand, and Mikes Carburators. They instruct you to remove the nozzles but don't show how . I am afraid that any scarring on the top notches caused by a screwdriver might ruin them. I am currently soaking the frozen in place nozzles periodically with PB Blaster and haven't tried to push them out yet. Hopefully someone can advise. Thanks
