I don't have much experence here but at the moment I have a Stihl MS021 my father in law gave me. He bought it New Years ago and it got ver light occasional use. Then about a year or two it became very hard to start. He bought the bigger model Stihl and the 021 just sat in its case. I got it running the first day he gave it to me but its still hard to start whether cold or after running for sometime. I think I'll buy a new carb and hope for the best. Sorry for the lack of info.
