Starting fluid is hard on motors. Especially new ones. I say before you go spraying stuff all over the place you should look into it some. Disconnect your fuel line where it goes into the carb or fuel rail. Get the fuel pump going and see if you have fuel there. If you do the problem is after that. If you don't have fuel its before that.
That will narrow it down. It should be mostly common sense after that.
This is all good training for when it dies on the side of the road in the middle of nowhere.
