I agree it sounds like its bin time but also empathise that at this point its more of a case of finding out why it isn't working more than anything else.

My guess (provided you have tried another plug) would be that cylinder base gasket not being perfect and its just not scavenging fuel right. But it must be pretty bad to not even kick

Mine is still going well. It sat for a full year until june. Fired up 3rd pull despite stuff all compression and did dirty work cutting crap Strellitzia palm down to underground.

Ended up dialling in the carby properly cutting biscuits of 12in bottlebrush branches.

As would be guessed by its internal condition, at optimum setting it was still faster than a very healthy 25cc Zenoah g2500 clone (ozito/gmc/909 arborist saw) but not by a massive amount given its got 60% more cc and has a 325 chain
