Ok, Bill =E2=80=93= you lost me.  Must admit my carburetor knowledge is a bit on the skimpy side.
 
However, in the car= buretors I recall =E2=80=93 when the float level was high in the bow that= meant there was lots of fuel in the bowl, when the float level was low in= the bowl the fuel was also.  Am I confused or did you =E2=80=9Cmissp= eak=E2=80=9D {:>)?
