Even more interesting. I pulled the starter down and it is seriously built like a tank. The starter on this little saw is built far stronger than the starter on the the 103cc Pioneer. There is no plastic and what looks like a brass bush that is grooved for lube perhaps.
The fast idle throttle lock seems to be linked to a decompressor. I guess these items might point to a high compression machine.
A few other owners have reported compression tests around the 180-195 psi. Apparently they then released a lower compression version where plastic components were used in the starter mechanism.
