My grandfathers 025 stihl and a cherry tree recently had a disagreement. Anyway, my local dealer sold me a used front handle and rear handle asy at a fair price. The only thing I had to buy new was the chain brake handle. I have it all (almost all) back together. The only thing I cant quite remember is how the ground wire and little metal tab connect with the master control switch. If anyone could try to explain it (I know this might be explain) that would be great. A nice pic would be even better.
