China scooter engines all the same?

[babo]

I've got one of these for a project, and can't find out the specs on this engine.

When I searched I found many engines that look alike, but with a different labeling sticker on the pullstart. Ive seen this engine called 22cc 33cc and 43cc.
Mine says QINGQI on pullstart. I can't find any other identification.

Pretty much the same motor no mater what name is on it from what i know. I have a old Kragen Zooma 31 or 33cc (don't remember) motor on my J-Dog build.
