Craftsman 42cc chainsaw - Compression too low?
Saw is from 2002. Light duty - sawing 3 cord per year. Starts and idles well. Bogs down on throttle up and with any load on 18" bar/chain. Compression is 75 PSI. Added 10 drops 90wt gear oil to chamber and got 95 PSI. Should it be 110 - 130 PSI? Does this sound like cylinder walls scored and/or rings stuck? Ready to be recycled? Thanks so much. Doug
