The 70cc Derbi Metrakit cylinder available on Treatland that costs $150 states "flat reed", but when I look at the pictures, I dont see any indication of an intake port. Does anyone know if flat reeds means case inducted or something?

The picture seems to show a slot along the skirt of the jug, but in other images, it's not there. What's the deal?
