Cliff Ruggles:
Being able to slow the engine shows some control, which is good.

I've never liked the .120" main bleeds.  I get more of those units in here than any other for custom tuning.  Just too much emulsion air, requiring too much main jet and not enough metering rod.  Even going that route the fuel curve goes lean.  The smaller airbleed set-up is a better deal, all the way around.....Cliff
