Repairing Engines for 6 months to Buy a Snowmachine

I have never worked on an engine before. But I really really want a snowmachine. My dad says I have to earn the money if I want to buy one, so I am repairing old broken snowmachines and snowblowers and selling them on Facebook Marketplace to earn money for my snowmachine. For the next 6 months, me and my dad are learning how to diagnose and repair engine problems and working on old snowmachines, fixing them and selling them.
