My hedge trimmer( McCulloch 2 stroke) cuts out on idle but runs fine on full
throttle but if I cut a section then go back to idle cuts out and difficult
to start unless I leave til cold again. Plug has been changed. I noticed
there are 3 adjusment screws. 1 I no for to speed the engine up the other 2
are marked "hi" and "lo".
Anyone got ideas I think just a tweak to get it right (I hope)

thanks
