The complete engine is dismantled and measured. The pistons do have a 0.30 size. This tells us that they have been renewed one day probably not too long ago, but we do not know. That is always the uncertainty of projects. Has been sitting for 20 years, but what did they do before.
We will make it all perfect. Want to have a smooth running engine.
