At the moment, I have a young man (senior in High School) who claims he wants to "learn small engine repair".
It gets better...
Normally I just call him to pick up the parted-out cores and chassis I have sitting around, but he called me one day and said he wanted to bring a mower over for me to "help" him with. I said great, bring it over. He pulls up then gets out and cranks the mower up on the trailer he had and immediately wants to know why it is surging badly.
The carburetor had only one bolt stud holding it on. I started explaining a little about air leaks and how the carburetor functions. His eyes glazed over and he asked again, "what do you think it is the problem"? I went on to explain how the venturi in the throat of the carburetor works and had him repeat what I told him. Again, he asked, "what did I think the problem was"?
It took a few more times before he realized I was not going to just blindly fix it for him without him learning what was going on.
Finally, I told him it needed a spacer gasket that the carburetor was attached to. He called me a week later and he had replaced the gasket and sold the mower.
He simply wanted to use me for free so he could "flip" the mower.
In the following weeks, I called him with some more equipment salvage, but I think he is only looking for stuff he can flip quickly with little or no work involved. He has not called me back or showed up since, so I guess time will tell.
It makes me realize now why the old mechanics I grew up around never talked much, they just said watch and learn if you want to learn. Not all were that way, but most were.
