John,
Can spot 3 problems straight away ! One is that the wing nut is at the back rather than the front where it should be , and also, assuming one is right handed, starting will be almost impossible , because the pull cord is on the wrong side of the handle ! And finally, the pitch of the teeth is far too coarse for normal use, which may explain why it was bargain. Assume they had run out of finer pitch versions ?
