Is there a recommended adjustment for the float? I have it set just bit closer to the carb body than level. Am I close? It runs but it has a slight miss. Due to the rain I cant take it out and test drive it. I will later if it there is a break in the weather. Saturday is the big wedding day. She needs to be at her best. 0 hour is 3:00pm tomorrow. Thats when we are leaving for the hotel. I don't think the hotel guests will like me walking down the halls stinking of gasoline because I had to make another on site adjustment!

Will:

Noting your earlier carb problem, be sure the small gasket is on the gas inlet valve and snugged up.

Have carb body upside down. Make sure float travel is free with a little side to side travel.

The float level is measured directly opposite of the float hinge. .... adjusting done by compressing or opening up the tang that contacts the valve , be sure it's centered where it contacts valve.

1/4" from the machined flange where the bowl gasket sits ( w/o the gasket now ) to the float.

Blow into gas inlet while carb body is upside down to insure valve is closed by the weight of the inverted float.

Should put you back in service...

Kiss the bride for me, oh I mean all of us on the Forum.....

That would be a lot of kissing guys! I'm afraid you would have to clear it through the wife first guys. I just don't see it happening.

Bob, It runs with a slight miss but because of the rain I cant take it out for a test drive. I think it will be ok. We will have a back up car just in case.

The float setting for the NH is 15/64 to 1/4" from the machined flange on which the gasket sits to the flat surface of the float across from the hinge. The below diagram shows how to make a qauge for this setting which is taken by holding the carb upside down. The gap is adjusted using a screw driver to open or close the tang which opens and closes the needle valve as the float moves up and down. If the gap is too wide, the valve will close too soon, before the cup is full and starve the carburetor. If the gap is too narrow, the cup will fill before the tang can close the needle valve and cause the carburetor to overflow, so this is one of the most important settings crucial to the proper function of the carburetor.

Check the Ford Service book. It doesn't get any clearer than that!
