Hi,
I'm new here. I'm in Sydney, and have offered to take a look at my son-in-law's chainsaw that hasn't been used for years.
I've identified the chainsaw by some web pics I've found.
It looks like a Pro Mac 610.
Bruce, do you still have access to piston rings for this model?
The rings are 0.75 mm thick and the piston is 47 mm dia.
Also, where can I get an operator's manual for this model.
Many thanks,
John
