Guys if the weedy is a yellow boom Ryobi it is really a Homey 30cc. Black boom weedy is a true Ryobi, produced by MTD. The Homey/Ryobi (atleast the one I have) must be a newer design because the cylinder has more fins and the porting is a little different. Mine spins an 18x6 @ 7000 and unlike my older Homey 30cc, will easily hand start.
