Fix a few lawnmowers, weedeaters for neighbors then let them know if they have old tools laying around you will take them. I have old saws at the farm that were given to me for years. Fixed a nearly new Poulan 2450 that was in the barn for 7 years, i was bored and needed something to do. Some fuel lines, carb kit and a chain now it runs great so i had to try a muffler mod. It screams now.
Being a gearhead/mechanic and a hoarder i have refound saws to mess with, much cheaper than racecars and fast boats.
Saws or most any 2 stroke tools are easy to learn, cheap, and fun/addictive.
Check neighbors garages, yard sales, and people moving. You can find saws cheap/free to feed your new found addiction.
Have fun.
