float level
I have a 75 f150 2wd with 390, holley 4160 4bbl....
I rebuilt the carb...seems to be running good...
I am having issues with float level on secondary bowl.
When i pull sight plug gas has built up and gushes out the hole.
And my adjustments dont seem to make a difference...
I adjusted the float all the way to bottom of the bowl and it still comes out the sight hole...
I checked the float in a pan of gas...it floated for an hour so i figure thats not the problem...
But...what is????

Okay.. I see. I suggest pulling the secondary bowl and double checking valve pin and the float spring.... seems like something is binding not allowing ya to have any adjustment.
