Starting from scratch

Hi Everyone. I’ve recently started a new job in a new field, engine machining, and want to learn engines inside and out. Do you recommend picking up an old simple engine to have on hand to practice the steps in this course? I’m a hands on learner and look to your advice.

It definitely helps to learn when you do it yourself rather than just watching and reading others. That's how I startedd it too. But we're all deferent...
