The only markings on the carb are a 42 stamped on the top, and 1.75 on all 4 butterflies. It is a doublepumper carb, 4 corner idle, downleg boosters, Idle-eze, no choke or choke horn, 76 jets in the front, 84 in the rear. I think its an 825 but not sure. Can anyone help me or direct me to where I can figure it out?
