I know my way around some farm/garden equipment and power tools, as well as a few things about older cars, but I am really not the mechanic in the family. My boy, on the other hand, is a journneyman mechanic. He has tried to teach me a few things over the years, but I grow impatient and just can't be bothered with the technical jargon. I am more of the "show me what piece goes where and I'll remeber it in my head" sort of person. I don't really care HOW a carburetor works, I just need to know where it goes. The rest, hey that's why I paid the big bucks for my son to go to school. It probably cost me far less to do that than it would have to pay a garage everytime I needed something fixed over the last 15 years, especially as everthing becomes more computer controlled with sensors and all that stuff.
