I'm 35 and reading spark plugs and tuning carbs is foreign to me. Widebands and Diagnostic codes are what I go by. You have to realize that by the time I started driving, carburators were a thing of the past. I also could not tell you if it was a 57 chevy, but, I bet there are cars I could point out to you that you didnt know. Knowledge is relative. While I hope my son will follow in my footsteps and be a car guy and do some boxing, I wouldnt force him. You must have passion. No one can make you.
