There was a recent post on the Q-list about the dimensions of the Continental O-200. Paul came up with a great link which shows several views of the engine with appropriate dimensions.
I am posting the pictures below just in case that link goes dead at some point. This should be useful to anyone building a Q-200 with the standard Continental O-200 engine.
Please visit the link posted in the description to see the guy who created these files. The SolidWorks version is not my work. (Just wanted to be extra clear.) :-)
