I'd point out to anyone bringing up Apex seals as a potential problem: You must not be familiar with using a conventional mini 2 stroke. Chainsaws, leaf blowers, etc require exceptional levels of maintenance and aren't exactly known to run well. Most of them are either running too rich or lean at any given point, and therefore are either building up carbon, or burning themselves out. Not to say there aren't some good ones, but small 2 strokes that this engine aims to replace are not exactly paragons of reliability. Also, most small 2 strokes have abysmal emissions due to running too rich/lean all the time, having badly made carburetors, poor tolerances, no catalytic convertors, low thermal mass, etc. This looked relatively simple to assemble, and would therefore be pretty easy to disassembler. My guess is that if there were any seals that needed to be replaced, it would be a relatively trivial job compared to a standard small 2 stroke. Source: have rebuild many chainsaws, weed whackers, and leaf blowers. Used to build go-karts.
