None.

Give it away and pick up some Echo or Stihl 2 stroke oil. The Lawnboy is a carbon growth hormone that creates more trouble than it's worth. Use either of the other two anywhere from 32 to 50-1. You could do the same with a good synthetic if desired, especially if you intend to use a synthetic later. Unless you know for certain that the connecting rod has bearings at both ends stay at 50-1 or richer for the oil mix. Bushed engines need more oil.

Tune the engine for good running and flight, no hovering or torque rolls for the first 4-6 tanks, and go fly. Don't try to run it on the ground for tank after tank for a break in. It's not necessary and it can be pretty hard on the engine, especially if cowled. Hot air exhaust area on the cowl should be at least 3 to 4 times the cooling air inlet area. You Edge has a curved lip on the bottom of the cowl if it's version II. If you open some of the cowl up aft of that lip, retaining the lip, you've done a very good thing and created a nice low pressure area just about where it's needed for hot air extraction.

Now go have some fun
