By using the new engine at low power settings you risk not getting the piston rings to seat properly. This could result in excessive oil consumption, reduced power etc.
I know how exciting it is to fire up that new engine but please follow the breaking procedures that come with the engine. Our airplanes are not “new” designs. We know that the Van’s airplanes taxi well etc.
Hire a known expert local small airplane mechanic to check out your aircraft and be there for first start. After 25 years and 11 airplanes they always find something, and that IS a good thing.
