48 IDA Float Settings

[jhirasak]

There is another method to measure the fuel levels in the bowls that was briefly described in the Weber Shop Manual. This method is similar to that used by Paul. The screen covering the jets were removed and the emulsion tube was also removed. Then, by using a vernier caliper as a depth gage, one should hold the base of the caliper on the flange exposed after removal of the screen and extend the depth gage until it just contacted the fuel level in the well. By taking measurement on all four carbs, one could determine which floats had to be adjusted and by how much. However, the Weber Shop Manual did not indicate what the measurement should be for the desired fuel level in the bowl. Does anyone what this distance should be for the top of the float to be set to 5.5mm above the bowl mating surface?

Perhaps it is more important that the fuel levels in the bowls be the same amount in each carb rather than a specific numerical value.
