it will probably be cheaper to replace then repair if you pay a shop to do
it, I would get the model & serial # off the engine and call a local shop
to get a price on a new pull start ass. if it bolts on you should be able to
change it no problem yourself. Also if you do get a new starter ass take the
old one in with you they should be able to tell you if the repair will be
more then a new unit.
