At break-in I did run approx one gallon thru my Saito 82 but if that's responsible for the smooth running 82 I have now it was worth the time and expense.

I swear that engine starts as soon as I start towards it with the starter (:-). I haven't checked the idle rpm since installed but it certainly seems to be turning over very slowly. I do own a tach so maybe I'll actually use it next time out instead of leaving it on the shelf.
