Borzak,

The engine must be broken-in this way:

When starting it for the first few times, use a heat gun to thoroughly heat the cylinder. This will make it much easier to start.


DON'T YOU EVEN TRY TO BREAK THIS ENGINE IN ON THE PLANE.
THIS, UNLESS YOU WANT TO BREAK YOUR PLANE.

There are engines that are not so tight, but if your engine is very tight, you need an engine test stand for the break-in to be done uneventfully.

You can get this one for a good price:

I believe you can buy it at the LHS..
