I have found over the last few decades, all over the world, that people that over value their skills and/or capabilities are often the people you want to leave foundering in their own self-import as you search for a true gem. Someone that has been damaged by an unforgiving life, now living with broken dreams, simply gets bitter and old. I "can" and "have" performed all these tasks out of occasional necessity, like most riders. I choose not to, just like I don't service the 6 cylinder connies that come out of my Cessna 180 float plane either. Thanks for your lack of real input but the question is where I Can find a great mechanic, not how to spot mediocre mechanics.
