G'day FAST GRASS
This saw has done many years as a full time falling saw Aussie hard wood then downgraded to a mill saw so more or less 10 years hard work. I gave it a full Rebuild a few years ago I use it most days but the last few months I run it say 4 hrs a day(workdays)..The carbon on top of piston is from running 25:1 and its always run that I cant pinpoint one oil for more or less carbon at that mix as its run a few brands of oil lol,but the bore is still like new and bottom end is good for anuther 10 years of work...Cheers.
