I have been tinkering with engines since about 2014 when i got a pressure washer that had not been ran in a long time. I spent time rebuilding the carb and doing a few other things then used that information to buy more broken engines to fix then sell. Once i turned 16 and had money for a car i took things to the next level and starting working on engines in cars. Since then i have done 2 Complete engine rebuilds, read countless articles, swapped engines, added turbos to engines and have often bought broken cars to fix and sell.
