Question
i have a 1936 ford with a ford{Holly} carburettor markings on side say ford also has a 94  and a model 59 markings on carb.   What is the float level and float drop settings supposed to be.The books i find say average float level setting is to be 11/16  +/- 1/32.but this will not work..And to get the float level do you turn the top upside down and measure the level at the top of the float and for the drop turn it right side up and measure the drop from the casting to the bottom of the casting

Answer
Ok, the way we did it in the day when i worked for Ford was to bench set the float level with the top off the carburetor and held upside down. The measurement from the gasket to the bottom (top when held inverted) was 1 3/8" to 1 11/32". Then we had a special Ford tool that was a glass riser tube that screwed into one of the plugs that you use to gain access to the main jets. With the engine running you looked for fuel in the glass to be 11/16" below the gasket surface. Bench setting the float will get you a good running engine. Good luck.
