Beats me. Johnsered is non-existent here. Been runnin my 372 today and vibrations are expected. They are down to hauling logs out now. By end of next week I will be on the cutoff pile like a lone seagull on a beached whale carcass.
All the logs are hauled away. This morning they were loading they heavy equipment. Now I have the cut-off pile all to myself, and cool temps this weekend.
I run a full skip, square ground Stihl chain on my 362 w/ 25" bar, especially on big logs. Just takes a bit longer to sharpen the square chain.
