ZDZ 80 is it too rich?
I keep getting black residue on the exhaust. what do I need to do? my Low is 1.25-1.5 turns my High is 1.25 open. what is the deal? it does hesitate when you go from idle to WOT, as if it was too rich but starts as a dream. I am hoping I can get some feedback.
thank you!

if the motor is new and your useung the recomended penzoil then all is good yes you could lein it abit on the top end but your not going to get rid of the resedue until you change oil
I ran 2 gallons of the penzoil then amzoil 100:1 mixed @ 80:1
5gallons then started to lein it out a little at a time

Black Residue in the exhaust is an indication that the engine is wearing, if this is a brand new engine then that would be what is expected as the ring seats - its normal for a new engine ! 
Every engine is different, depending on the tolerances of the particular pieces, Some of the ZDZ engines in my area have taken 3 hours of running to fully break in, some take more, some take less, at the end of it all, expect this engine to give upwards of a thousand hours before you have to replace anything you didn't fry by running lean, wear by using dirty fuel or allowing dust or dirt in, or bend by running an unbalanced prop or crunching the dirt with it ! Enjoy your engine, its among the top in its class.

you said you think your still rich!
Do Not Run This Motor On The RICH Side.
set the low and high needles with it running so you get the best idle and best high end rpm.
if you run it rich it will varnish the piston and cylinder and make the engine even tighter than it is when new.
just try to get the best performance you can by agusting the high and low settings and you will be more than happy after about a gallon of fuel.
p/s
make sure you have the proper oil and oil mix.
