Pull the spark plug out and if you can't turn the crankshaft with the

If you really did put oil in the gas then this is a fairly rare failure.
Don't pull it apart, get a replacement engine from your seller.
Let us know how they treat you.
Did you take the head off or any part of the engine apart before you started it?
