My mower has a dial that is supposed to allow you to select the speed the mower self propels. Mine does not work unless it's turned up about half way and then it takes off at full speed. Turning the dial up or down from there results in no change, just full speed. I tried the cable adjustment on page 13 of the owner's manual, but there was no change. I'd like to fix this myself. Any ideas?
Thanks in advance,
Barney
