Well, I am pretty mad right now. I went to a local machine shop and they told me to put my motor together that I would have to bore it and buy new pistons or they wouldn't do it unless I spent $1600!!! I could buy a decent b18c for that!. F-THAT! I know my parts are fine, so whatever.....anyway....I know how to assemble it minus the piston rings....I know you have to file them to fit....could anyone give me a link to a walkthrough w/pics? That would be great! How does one file these down to fit??? Any insight would be appreciated!
