Use a tap ie from a tap and die set, i think its half inch or 13mm this will cut a thread in the copper bush and gradually twist it out, worked for me before. Soak the new bush in oil overnight. Then use a bolt with a nut screwed a little way down and tap it in with a soft hammer, make sure it goes ins traight at the start. Buy two bushes so that if your first attempt goes wrong you have a second chance and can learn from the first attempt, they are cheap

TIP: Don't put bushes in the tool box - they are very soft and will get trashed..

screw extractor number 6 or 18/25 size (imperial) works a treat for bush removal, only needs the slightest twist (left hand thread) to bite in then bush pulls out easy (did so on a relativley un worn bush with lots to bite into). Also can be used to fit new bush, lightly bite the extractor into the bush to hold it the atarter motor hole as square as you can, and push in (small mirror and light helps to check) then reverse the screw extractor to remove it leaving the bush seated. tap it home GENTLY with the square reverse end, maybe a wooden dowel would do it better so as not to damage the bush.
