For the 2nd saw, you mentioned replacing bearings. The sealed bearing and gasket kit is about $80. I just got a new loaded shortblock for $110 shipped. Hardly worth putting bearings in the old case for such a slight cost difference.
I’d personally run a little richer oil ratio. This was a 2017 model run on 45:1 with XP oil
