my mate next door had an old homelite saw,,it worked well,,i did a few repairs on it,,then it lost spark and we couldnt get another coil for it,ive got a little sachs saw thats a demon(bit souped up)and an old big stihll thats a bigger demon(a bit more souped up)years ago my mates dad had an old canadien saw without one piece of plastic on it,thumb oil pump,it sounded like a bultaco with a heavy flywheel,i still like the two stroke weed wackers,i think they spin faster,some of the cheap new ones have non adjustable jet screws,or a funny recessed one requireing a special tool,so when they run bad they stay bad.
