A SkyHawk is a China girl.Should I start with a chinagirl or get a skyhawk?
Do you know anyone with a Chinese engine to be able to compare them, or one of the later model number KR?
Ludwig was talking about comparing to the Russian D motors.There's really only 2 Chinese engines, the 48cc and the 66cc. Power hardly varies from engine to engine. A stock 66cc is hardly different from another stock 66cc.
Do some googling....... Pull starts break all the time and centrifugal clutches are tricky to get right. You can always add those parts on later.
