Yeah I ran Green Machine and Fuji Robin to start with. Then Shindaiwa for years. Then Stihl for a lotta years until they started changing things like casting the flywheel key as part of the flywheel and switching to 4-mix. A lot of people I know went 4-mix and stayed with Stihl. I was ticked off I couldn't get another FS85 lol. I was really loyal to my dealer at the time. They had Stihl, Echo and Redmax. I bought all new Redmax stuff and never looked back.
