Your engine came with a manual and it has information regarding the proper break in of a engine.

The main importance is as few starts as absolutely necessary and definitely no taxi tests!!

Can you please expand on this? Why does the engine only require a few starts and no taxi test?

I'll share why no taxi tests. I was advised that during a hight speed taxi test, you could find yourself flying before you are ready. In that case you may not be prepared for flight and may end up bad.

When I first took off for the first time, I was ready and I was told that my wheels were off the ground in 3 seconds. Not much time.

It does not take much effort to fly these creatures.

I would make that, no high speed taxi tests.

Think about it, if something were to not feel right you're just going to pull the power and stop. If not, your going to let it fly. So the high speed taxi test is just accomplished on your take off roll. Be prepared to pull the power if it gets squirrelly.

You can, and should still taxi some small amount to set the brakes and make sure all is working.

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.
