Let me know how you make out. I have similar issues with my 44's. Some sneezing and backfire at low throtle and decilleration. I changed from 55 to 60 idle jet. My mixture screw was 1/2 out instead of the recommended 1 full turn out. Thought I would check out plugs for heat range. I am using Champion 3025's. Waiting to hear if another plug is better?
