The instructions are a bit ambiguous on how to measure the float. The early type float and late type float are measured differently. Our problem is we don’t know what the difference is. We assume we are selling the late type of float seeing the instructions were done in the 60’s & 70’s.
Bottom line is whichever one you use the float will be almost level when done.

Match your float using your carburetor number.
