Have you reviewed posts on this issue in both the "HPo" and "Engine & Driveline Shop" sections? This question is one of the most commonly ask questions on this forum. I would pay attention to posts by 'Carbking', as he is in the carb business and is a 'Guru' on this subject, not to discount others who have "been there, done that". Good luck.
