Some has got to know this one....

QUESTION: 
......On HS carbs that have a crankcase breather connection
between the butterfly and the piston....
Sure the pipe nipple fits the breather hose, but down in the body of the carb 
the
hole is only drilled through part way. the hole into the carb throat is a small
diameter restrictor size. DOES ANYONE KNOW WHAT DIAMETER HOLE SIZE
IS USED?

I need to drill and tap a pair of carbs for this config, and I need to know 
the diameter of the orifice hole. Obviously the outer reaches of the hole fit 
the breather pipe
nipple that is pressed into the body of the carb. WHAT'S THE SMALLER
HOLE SIZE DOWN INSIDE?
