i did have one with a simillar problem , it too was going to be scrapped but a mate wanted something for own use ONLY and asked if he could have it , so i warned him to keep checking things , look for more cracks and bin it if he found any , that was i think 5 years ago and its still running strong cutting bush block he has . but i sure wouldnt recommend selling a thing like that ever

. if its for your own use maybe keep it if it runs well until it dies but dont move it on

.... keep safe
