I was using my 462 yesterday, felled a couple of 20" trees the day before, then set about cleaning them up...it was hot (28c ish) and my saw started to run a bit rough then conk out. I wondered if it was trying to reset to the hotter temperatures? After about 20 mins or so it seemed to settle down again.
I didn't have the manual with me to check about resetting the carb.
However, suffice to say, I picked that saw up in preference to my 260 to limb and buck smallish branches for firewood, it is just so nice to run!
