* or 10 mph and also try using 1/2-3/4 choke.

You should look at the plug and see what it looks like, (brown to black is good, white or grey is bad)

Some discoloration is normal, but heavy discoloration can be an overly lean mixture, which can also cause hard starting. A lean condition can be caused by an air leak between the intake and the cylinder, which is not uncommon.
