Why do some Stihls have a red master control lever? I have heard the saws with the red switch are old but I don't think that is true. I have a 1986 024S and 1988 034S and they have a black lever.
I am Not sure I know the answer, but I have an Older Model 038 which had a red lever, I recently ordered a replacement by the same part number and it was black. It fit perfectly and worked fine.
