Some update and more questions.....
On a recent trip I passed one of the older dealers in Mass and purchased a 028 block with the brake and got it home to find out that it doesn't fit my saw. It has the wrap around band. So back to the drawing board. I talked with Stihl who explained to me that on parts that are NLA, any dealer can ship them out of their territory. So, back to square one and getting the 1118-007-1002 shipped to me. I had the retailer that had this kit send me a picture and I noticed it included a brake handle without the two windows. Does this mean that this kit IS NOT an intertia brake system? Does changing out the handle change any of this?
