I finally started with my own little engine project. I will probably set up my website to contain the pics and ask questions on the forum as I go along. I will post a link here as soon as I get it set up.
So far, the opening up of the engine has been easy. All bolts got loose with just as much as a push and no nasty surprises inside... More on the site:
I now got together of parts I need and sent it out to a few companies. I hope it all works out - you can follow it on the website, I try to update it at least once or twice a month (or more often, if I get time to do something)
