What, in God's good name, does good punctuation and grammar have to do with a man's ability to rebuild injectors? I certainly would rather have a mechanic that knows his work and does it well than one that can spout Shakespeare and write like Keats. I am dyslexic and a hopeless speller but I can do quite good mechanics, welding, fitting, etc., etc. And I'm a pretty nice guy on top of it. And modest too.
