Yep....and when the low speed needle is too close to the nozzle, the high speed
needle is non-operative that is to say it isn't working. They have their main
needles set at 6-7 turns out....they could turn turn them out even further and the engine
will not richen up.

They can turn it out until it falls out in their hand....it will never richen up because the
low speed needle is now a "regulator" and will not allow enough fuel through. I tried
to explain this to the fellas, but they don't get it.

I proved through my own testing (what I already knew) once you get the low speed needle
far enough away from the nozzle for the main needle adjustment to work properly, the
low speed needle can be backed all the way out, and have no effect on the high speed.

They claim that if you get the low speed needle up close to the nozzle, it will somehow
increase the flow....while if you get the low speed needle away from the nozzle, the high
speed doesn't work right, hence the 6-7 turns out is where they had the carb set.

Oh, well.
