Spent time running engine and adjusting the mixture like goldylocks too LEAN and too RICH and then just right to make sure I was somewhere in the neighborhood of a tuned carb and that the engine would run well enough to be safe. Still not convinced it's perfect - it's too hard to tell with a new engine on the ground, but I know it's not too lean (make things psycho hot and damage engine) or too rich (not enough power..) so it's time to go for it. Attached the cowling, which is a pain, and before doing so connected an interface cable so I can easily plug the plane into the battery charger from outside, the cable plug hangs 2" from bottom of cowling when out, and tucks in nice when put away - very slick. Inflated tires, I'll go with a high 50psi to avoid the low pressure tire skid pop phenomenon. Ready to roll for 1st flight! Took some great pictures of the final product.
