Chainsaw Repair

I am fortunate that I do this as a hobby. I draw a comfortable retirement and I love to stay busy doing what I enjoy.
I would hate to have to depend on working for the public, again, to pay bills.
Today, I don't work for the public, just buy chainsaws, hedgers, trimmers and blowers, repair them and sell.
In the last three years, I have not been to a dealer for parts. I buy on CL or eBay. Many times, I am able to repair a part or make a new one. Many people can't do that but I am a retired Tool&Die Maker with some good equipment.
