I am looking for the re-coil(starting) assembly on a 031AV Stihl. I had it off to clean and evidently did not re-tighten the assembly holding bolts properly. My neighbor used the saw and when he put it down I noticed that the assembly was missing. I could get new but it is more that I bought the saw for. Any ideas or parts saw to purchase would be great! Saw cut great and would like to use it again.
