had first hour or so of use today. went well. like a hot knife through butter. it tends to die if you have it on one side, but not the other, unless the fuel tank is really full. spark plug lead also prone to snagging in denser thicket.
only time it smokes a bit is on the frst few revs. after that, no more smoke, runs perfect.
on the whole i am happy with it. lubed the cutters with some used engine oil after it all.
