Technical Floats on a Holley (Ford)

Just bought a rebuild kit from Mac's and It has NO instructions, exploded ***emble or float settings. Came with a gauge..... Thought I had an old copy, but could not find it. What are the settings procedures, float drop and shut off ?

 

It would help if we knew what kind of Holley. Maybe look for a YouTube video?

 

Not enough information to give any good answer. X2 on a you-tube video based on the model number.

 

Ruff rules of thumb`any carb;,with float inplace an with needle closed/on seat> float should look level to carb body.
Always check old floats for leaks/cracks or holes.
Idle jet for most,good starting point is 1.5 to 2 turns off closed,same with ****erfly/gas linkage.
Adjust as needed. Have fun.

 

I run a handful of the Holley ford 2v s on my coupe and dealt with a couple acting up I found the settings online I may have em but the float barely moves when set right and until they're right they run over etc I made a little gauge or template to set em and almost no fuel pressure couple pounds .. I'll check back with a pic of the template from the garage

 

I have given an answer to this in previous posts. If it's a Holley 94 as used on most stock flathead Fords the running level of the gas should be 11/16" below the gasket surface of the bowl. The only way to check it accurately with or without one of the worthless gauges that come with most kits now is to use a standpipe gauge such as the one K.R. Wilson made. Extremely hard to find now. You can do as I did and make your own using a spare jet access plug with a 1/8" hole drilled through it. Solder a short piece of 1/8" copper tubing into the hole and slip on a piece of 1/8" clear vinyl tubing . Screw the thing back into the carb and affix tube in a vertical position as close to the carb as you can. With the car running, you can see the level of the gas in the tube. Old floats are usually stained where they sit in the gas. You can use the stain for a starting point to set it. With the top of the carb upside down and gasket in place, measure from the top of the stain to the the gasket. This is the old way of setting these things accurately and it's trial and error, fiddly and time consuming but very accurate. Be very careful about bending anything on these floats. They don't like that and are very easy to damage. You can lower the fuel level by adding a second gasket under the needle seat if necessary. Set the idle mixture using a vacuum gauge or a tachometer to get the fastest idle speed then adjust the speed to suit. The float drop is not normally an issue as long as the needle opens.
