The local small engine go-to guy has asked for help fixing the pulled threads in an MS250 Stihl. Owner has already "fixed" it by first using red Loctite then tried screwing 7/16" bolts into the case. Of course neither worked and now the holes are off from their correct location and no longer perpendicular to the surface the bar sits on.
I like a dimensional print but mainly need the center to center spacing of the stock stud locations. Hopefully, the holes can be straightened and brought back their correct location in an oversize form to accept either a commercial thread insert, step-studs or tapped for a blank and the holes re-drilled to the factory size and thread.
