We've bought two of these machines over the past year... a 52 and a 62CC model. The 52 has worked hard with no problems at all. The 62 stopped running recently.
It runs a HUAYONG carby - pulse driven from the crankcase. It turns out that the genuine pulse tube - (5mm)showed some signs of damage and the carby membrane gaskets had failed, stopping fuel being siphoned up from the tank. The 5mm tube came from a Kawasaki dealer (oil line) and the gaskets were pulled out of an old Ryobi whipper snipper, the parts internally being identical. I'll find a new replacement set of these prior to full assembly - but the unit is running again - and well. Oh - and the tuning is similar to the Stihl... wind the H and L screws ring in and then back them out 1.5 turns. The L setting was further adjusted by about half a turn with the engine at full revs.
Thought I might share this info here for the next person who strikes these problems!
