You dont need to pull the engine apart.
Take the muffler off and look at the piston and bore in there.
Take the inlet manifold off and look in there as well.
Pull the starter off and look at the bottom of the bore and the skirt of the piston.
If its all dry in there spread a bit of 2 stroke oil love around inside the crankcase of the motor before you put it back into service.
The only way you would seize it would be with no oil in the fuel or if you got it really really hot. Perhaps a lean out due to a partly blocked jet would do it.
