My little Mantis starts every time. Turn to on at handle. Give the bubble a couple of pokes. Pull out the choke. Gently but firmly tug the starter cable - maybe twice til it makes a dainty cough to indicate she is ready to work. Stop. Push in choke. Tug starter again. Should go OK - give it a few seconds and then rev her up. The people at Mantis have a high reputation for helping customers, so if this doesn't work, ring them.
