A small piece of advice.

On the first run be sure to run the engine until it comes up to operating
temp inside the rotors.
I( you don't it will foul the plugs to the point you have to replace them to
ever get it to start again.
I think this is becausr of the lubricant they use in assembling the engine.

you need to burn it all off before shut down.

Been there, done that and got the t shirt.
