I have to admit, Lawyergong has a point even if made in jest.
A 2 stroke petrol engine is generally a 2 stroke petrol.
As long as its not overly portly for the displacement,
is correctly jetted (the carb)
and the ignition is reliable is there a major difference.

So I'l jump into the camp that says, if you're a petrol engine newby and you want little hassles, buy an established brand.
If you're an expert two stroker then anything will do.

If you';re not an expert, but want to save on engines then befriend the local scooter mechanic. All it takes is a few cases of beer and you've made a chum for life who will tune that carb to perfection.
