Yes, there's some confusion going on about the carbs. We will try to help you through it. There will be a "LIST" number on the airhorn of the carb. If you could post that it would help. As far as the metering plate goes I will say there are a couple options you can do. The easiest one, Quick fuel makes a replacement metering plate that takes Holley jets, but will fit under the Holley float bowl. Available at Summet, Jegs, etc. Another option, the metering plates have an I.D. # you can use to find the specs you currently have, then you can try to find new or used plates with smaller main jet holes.
