How I stumbled on this was Dave Dudek had some modified carbs for one of his hemi's in fast and on my Dyno he had a bad stumble. He sent the carbs back to the builder and he put larger squirters in it only to make the problem worse. So I got out the old carter tuning book and read it and that is what they said to do. So I pulled the squirters out and apoxied the hole shut and then re drilled them to over half the original size and bingo it worked. I now am a believer. Hope all works out for you. Jake
