+1 on running your engines at home before heading to the field on any new build, rebuild or engine swap (new engine or used engine it doesn't matter). Home is the place to get the little bugs out. The other thing I like to do in conjunction with testing and tuning the engine in the airframe is to do a Taxi test of the plane in my yard both on my paved driveway and on my lawn to simulate both types of runway. Just another thing to have the plane truly ready to fly when you do head to the field. Looks like you had a nice sunny day today in the" great white north", it was overcast and sorta crappy here in the "tropical west Georgia" area today but I flew anyway. Looks like maybe next weekend for your new bird? Yes? It looks good.
