Default Smokey: is it my mixture?

Pretty new to the list. I'm in Oregon and my (2) grubbees share 60 mi/wk average; 10 mi of which is uphill. Thanks for this great free service.

After some engine failures I ended up replacing one Skyhawk unit w/a new one.
I'm getting a whole lot of smoke and black liquid sputter out of the muffler. It is evident on the crank arm and my shoes. I'm about half way through my gallon of break-in mixture. I'm running 7.1 oz of Sthil 2-cycle oil to a gallon of premium
My Q:
Is this by any means normal for break-in or otherwise?

Thanx in advance
