Re: Which mechanic category are you in?
Self taught. First OB I tackled was my (daddy's) '55 or so Scott Atwater 10 hp (green and gold) as a teenager. Been interested in engines since a teen and have done my own work on everything I have owned, less machine work which I took to a machine shop when required. List includes cars, p/u trucks, OTR 800 cu in 400 hp Cummins and rock bucket, motor cycles, 2 and 4 cycle, lawn equip of all sorts, marine engines and outdrives in 2 and 4 cycle, and farm tractors through a JD 4230 400 cu in, 100 drawbar hp.
I didn't go to repair shops because I am electromechanicaly curious and didn't want to spend the money, nor wait out the period to have some one do my mechanin for me. Over the years I have accumulated a reasonable set of tools and a nice shop in which to work.
I buy manuals to provide specs for what I work on and if it's not in the manual, or unclear I go to www forums and ask question. I am a senior citizen these days and some things I can't remember and some others I try to remember and goof. Nice thing about forums is they are self rightening....if someone tells a lie they get jumped on with both feet....so the general public usually gets a truthful answer and that's the way it should be.
