OK, so maybe the consensus is that the motor he has is older (manufactured a while ago) rather than being a 48cc (since the head bolts are 10mm). I just started this hobby this spring, and all I have seen are newer motors manufactured in 2010/2011, they all seem to have larger head studs than exhaust/intake studs.
