I got one of these to examine it. It appears to be a Tiawanese copy of a Kioritz (Echo) with the mag mounted to the cylinder. Short shaft with the blower wheel mounted with a bolt. Lots of finning on the cylinder, no throttle, primer bulb and choke. Appears to be well built. I suspect these are the same engines available on one of the power skate board sites. California certified with a special tool required to adjust the mixture screws.
