Hi again. Quick little question, if I may. This is for a friend at work. He told me today that he has a Husqvarna 365 Special chainsaw that needs piston and cylinder. He was quoted $500 CAD at the local shop for replacement parts. Would anyone recommend using aftermarket parts to repair this, or best to use factory. If using aftermarket parts, where would one recommend buying them from. I will pass the information on to him. Thank you for any help.
