Topic: adjusting carb float


fordmerc    -- 01-07-2011 @ 7:07 AM
  In order to adjust the carburetor float properly, I have read conflicting instructions: a re-builders website measures from the base to the "bottom" of the float when the body is upside down and the float seated (1 3/8 to 1 11/32).
The Ford Shop Manual measures from the base to the "top" of the float under the same circumstances using a special Ford tool (size not stated).
I don't have a fuel level gauge.
Which is correct?

  To add further confusion, the rebuild kit I installed in my '51 truck furnished a gauge graduated in in 1/32" increments. My factory manual gives the measure in hundreds of an inch.

  Here is a pattern for a float gauge that I received well over 60 years ago. Place the base of the gauge on the surface of the upside down carb top, and adjust the float so it falls within the slot.

  Here is the thread from a November with more detail including my diagrams from the repair manual:

  My pictures from the previous thread seem to be gone so I'll post them again here.

Here are the instructions with diagram.
I just cut a gauge out of card stock inverted U shaped so it touched the carb body on both sides of the float.

  Here is a picture of my two-legged inverted U gauge I just cut out of card stock with the two critical measurements marked on it illustrating how it's used to set the float. The correct float level is given in Ford specs as decimal inches: 1.322-1.353 inches. 1 3/8 inches is just a hair beyong that range. 1 5/16 is right in that range. I like the two legged gauge because you don't have to worry about any "rocking" of the foot of the one legged one.
