The engine was bought in the US and was shipped to Croatia. It was
indeed bought in the crate (its packed in a big thing like a
refridegator) and just arrived in Croatia. I live in the UK, and will
be using it in Croatia for the holiday of 10 days, so when I arrive
there, I will have to unpack the engine, get it ready, and use it.

If there is a manual online, then it would be great to read it. Or any
kind of FAQ about engines, since I will be unpacking the engine during
my brief vacation. That is, the engine should be good-to-go almost soon
as I arrive.

Thanks
