With the air horn upside down you measure from the gasket to the bottom of the float. It should be 1 9/32 on all model B's. A longer distance lowers the fuel level in the bowl. You wouldn't want to taylor the adjustment very much. Too low of a level can cause hesitations & bogging. A high level can cause a rich mixture. I believe the drop setting is 1 3/4 with the float hanging. You bend the tang that contacts the needle seat.
A wet setting is the best way but I don't know how you would do it on that carb. I don't understand Builders method. Most Holleys can be set wet with an external adjustment.
They say money can't buy happiness. It can buy old Chevy trucks though. Same thing. 1972 Chevy c10 Cheyenne SuperIn the Gallery Forum | | |
